GRIND CITY OS
The User Manual
Everything on www.grindcity.org, explained — the desktop, the widgets, the GCM26 archive, Mane Street, Photo School, Bluff Book, your account, and the Admin panel. Every section heading carries a QR code that jumps a phone straight to it.
Grind City OS is the home of Grind City Meet — Memphis's photographer community, celebrating ten years of exploring the city. Instead of a normal website, the whole thing is a macOS-style desktop that runs in your browser: a menu bar, windows you can drag around, a dock, widgets, a chat room, and apps.
The first time you visit www.grindcity.org you'll see a short boot screen (the crowned-G logo with a progress bar), then the desktop fades in over the "Bluff City Dusk" wallpaper — a Mississippi River sunset under the M-shaped Hernando de Soto bridge. Everything you can see can be clicked, opened, dragged, or rearranged.
- Open an app — click its icon in the dock (bottom), or double-click a desktop icon (top-right). On a phone, a single tap opens things.
- Move a window — drag its title bar. Resize — drag any edge or corner.
- Close / minimize / zoom — the red, yellow, and green traffic lights in the window's top-left corner.
- Search everything — press ⌘ Space (or click the magnifier in the menu bar) for Spotlight.
- Sign in — the red Sign In pill at the right of the menu bar.
- Change the look — Control Center (the sliders icon) for Dark Mode and brightness, or Settings for wallpapers.
The strip across the top works like the real thing, left to right:
- ⌀ Aperture menu (far left) — About Grind City OS, Settings, Sign In / Sign Out, and the power controls: Sleep (click or press any key to wake), Restart, and Shut Down (with a power button to boot back up).
- App name — bold, shows whichever window is focused ("Finder" when none).
- File / View / Window / Help — real menus: close windows, switch Light/Dark, change wallpaper, minimize/zoom, bring all windows to front, open the Read Me or this manual.
- Sign In pill / account chip — signed out you get the red Sign In button; signed in it becomes a circle with your initial. Click it for your name and role, Open Admin (staff), Manage sign-in, and Sign Out.
- Wi-Fi & battery — decorative, like a good desk plant.
- Control Center — Wi-Fi and Dark Mode toggles plus a brightness slider that really dims the screen.
- Spotlight — the magnifier; same as ⌘ Space.
- Clock — always Memphis time (America/Chicago).
- Drag a window by its title bar; it can't be pushed above the menu bar.
- Resize from all four edges and corners (look for the cursor change).
- 🔴 Close removes the window. 🟡 Minimize shrinks it into its dock icon — click that dock icon to bring it back. 🟢 Zoom (or double-clicking the title bar) toggles near-fullscreen.
- The focused window is brighter; clicking anywhere on a window brings it to the front.
- Some windows have an ↗ at the right of the title bar (like GCM26) — that opens the same content in a normal browser tab.
The dock floats at the bottom: Finder (Past Events), Mane Street (the trolley), GCM26 (the aperture), Gallery, Maps, Bluff Book (the photo album), Settings, then Admin (staff only) and the Trash. Hover to see the magnification effect and name tooltips; a small dot under an icon means that app is open; launching an app makes its icon bounce. On phones the dock scrolls sideways.
Down the right edge of the desktop:
- Past Events — a folder that opens a Finder window of the archive (GCM26 and the Instagram walk archive).
- GCM26 — the 2026 anniversary walk, opens in a window. Right-click it for "Open in New Tab".
- Gallery and Photo Drop — the community photo wall and the submission box (see section 12).
- Bluff Book — build your own portfolio website and walk away with the files (see section 13).
- Book a Stay — suites in the Exchange Building (the start line of every walk), with a Get Directions map to 9 N 2nd St.
- Memes — a folder pre-loaded with the internet's top 100 meme templates, streamed live from imgflip. Click one to view it big; right-click to save a copy.
- Read Me — a quick orientation document. User Manual — this guide.
- Instagram and Linktree — the ↗ badge means they open in a new browser tab.
Single-click selects (blue label), double-click opens; on touch screens one tap opens directly. Right-click the empty desktop to change the wallpaper.
The stack pinned top-left is live, keyless, and tuned to downtown Memphis (the Exchange Building, where the walks start):
- Weather — current temperature in °F with an animated condition icon, plus a three-day forecast. Data refreshes every 30 minutes from Open-Meteo and the last reading is cached on your device so it paints instantly.
- Air Quality — the US-AQI arc meter with a needle across the six EPA bands (Good → Hazardous) and the current PM2.5 reading.
- Gauges — two rings: humidity right now, and the chance of precipitation today.
On short screens the lower cards bow out first; on phones you keep weather, calendar, and reminders.
The calendar shows the current month with today ringed in red. Days with a gold dot are Grind City Meet events — click them: they open the event's registration page. The footer always shows the next upcoming class.
The Reminders card ("Photo School") lists all four sessions of the photography series: past classes are checked off and struck through, upcoming ones sit with open circles. Every row links to the library's registration page.
GCM26 was the 10-year anniversary photo walk — Sunday, May 3, 2026, a ~0.8-mile loop through downtown: the Exchange Building → Stereo Alley → the Sterick lobby → First Horizon → sunset on the Rendezvous garage roof → back to the Exchange for the after-party. The entire live event site is preserved exactly as it ran at www.grindcity.org/gcm26: the interactive route map, all five stops with photo tips, the timeline, and the after-party details.
Open it from the GCM26 desktop icon, the dock, or the Past Events folder — it runs inside a window (drag it around while you browse the map), or hit the title-bar ↗ for a full tab. Tap any stop card for its photo tip and map links.
The trolley in the dock opens #mane-street — but first, the room dials in: a full 56k modem handshake plays over a Grind City Online sign-on screen (dial tone, the digits, the screech, the static — all of it, about 28 glorious seconds). Impatient? The Skip the handshake ⏭ button connects instantly.
Once you're in: pick a handle (2–18 letters/numbers) and pull up. The room is live and ephemeral: messages are broadcast to whoever is in the room at that moment and never stored — when everyone leaves, the room forgets. You'll see "pulled up" and "rolled out" lines as folks come and go, and the header counts who's here. There's a gentle rate limit (one thought at a time). Be cool.

Register on the library calendar, or just click the gold-dotted date on the desktop calendar widget.
The Gallery(in the dock and on the desktop) is the community photo wall — everyone's approved shots in one grid, each with the photographer's credit. Click any photo for the full view with its caption and credit; Instagram handles link out.
To get your work on the wall, open Photo Drop(desktop icon, or the "+ Submit yours" button inside the Gallery):
- Drop your pictures onto the dashed zone — or click it to choose files. Up to 5 at a time, JPG/PNG/WebP/GIF; big files are slimmed automatically before upload.
- Caption each shot (optional) and enter your name (required — it becomes the printed credit) plus your @instagram if you want it linked.
- Submit. Your pictures land in the review queue; a moderator approves what goes public. Staff uploads publish instantly.
Moderators curate everything from Admin → Gallery: approve or reject the queue, edit captions and credits inline, unpublish, or delete — so the wall stays sharp.
Every photographer needs a book. Bluff Book (in the dock and on the desktop — the photo-album icon with the red ribbon) builds you a complete portfolio website in about two minutes, and you leave with the actual files. No subscription, no platform, no account needed. Five frames on the film strip:
- Who — your name, where you're based, what you shoot, and what you offer. Bio and tagline are optional: leave them blank and the house AI writes them from your facts (it never invents credits you didn't claim).
- Shots — up to 16 photos. They're resized and stripped of location metadata in your browser — your photos never leave your device. Star one as the hero shot; captions become the alt text Google reads.
- Look — four papers: Gallery (clean editorial), Darkroom (black with safelight red), Film (warm cream serifs), and Bluff City (Memphis dusk gradients) — or pick Let it develop and the AI reads your vibe. Every look ships with both light and dark mode.
- Develop — the darkroom writes your copy: tagline, bio, SEO title, description and keywords, social-card text, and per-photo alt text.
- Your book — a live preview of the finished site. Flip the paper, accent, or default mode, add your domain if you own one (it gets baked into the SEO tags and sitemap), then hit Download my website (.zip).
The folder you download is a finished website: index.html, your photos, a custom-designed social-share card, monogram favicons, and a sitemap + robots file so Google can find you. Publishing is drag-and-drop: unzip it, go to netlify.com/drop, and drop the folder in — live in two minutes, free.
studio.html is your negatives. That file in the folder is a complete editor that runs in any browser, forever: add, remove and reorder photos, edit captions and copy, switch the look, set your domain — then re-download the updated site and publish it the same way. Keep studio.html safe and you can always rebuild everything.
After the download: the full go-live walkthrough — hosting, GitHub + Vercel, custom domains, and copy-paste AI prompts that do the whole thing for you — is at grindcity.org/go-live (printable PDF included). And the Mane Street chat room is full of people who've already done it — ask.
- Click the red Sign In pill in the menu bar (or go straight to /login-link-passkey).
- Enter your email and hit Email me a link.
- Check your inbox for the black-and-gold email from mane@grindcity.org (peek in spam the first time) and tap Sign in to Grind City OS. Links work once and expire in 15 minutes.
- You land back on the site signed in — the menu bar now shows your initial in a red circle.
The same page is your account panel when signed in: your name, email, role, passkey management, and Sign Out. No passwords exist anywhere in this system — just email links and passkeys.
A passkey lets your device's Face ID / Touch ID / PIN sign you in with one tap — no email round-trip. After your first sign-in, on the account page click + Add a passkey on this device and approve the browser prompt. From then on, "Sign in with a passkey" on the sign-in screen is instant. You can register one per device (phone, laptop) and remove any of them from the same page with the ✕.
Staff (moderators and up) get an extra gold-shield Admin icon in the dock and in the account-chip menu. It opens a window with these tabs:
- Users — every member with their avatar, name (click to edit inline), email, passkey count, and last-in date.
- Open a profile — click anyone's avatar or email for a full profile drawer: last login, login count, last seen, last IP, join date, passkeys, and their recent activity.
- Invite by email — type an email, pick a starting role, hit Invite; they get a branded invite good for 7 days.
- Shareable invite link — pick a role and hit Create link; it copies a `/join/…` URL you can text to anyone. They open it, enter their email, and get a one-tap sign-in link (then add a passkey). One link can onboard many people; links show usage and can be revoked.
- Change a role / Suspend (1/7/30d) / Delete — per-row controls; guard rails apply (see the next section).
- Roles & Permissions — the live permission matrix: 11 granular permissions × 4 roles as checkboxes, each with a plain-English label. Super Admins toggle any cell; changes apply within a minute.
- Gallery — the photo-curation queue: approve/reject submissions, edit captions and credits inline, unpublish or delete published shots (see section 12).
- Audit Log (Super Admins only) — every action and login event across the whole site, newest first: who did what, to whom, when, and from which IP. Filter by action type. Login/logout, invites, role changes, suspensions, deletions, permission edits, passkey changes, and gallery moderation are all recorded.
- How To — this manual, embedded, with the PDF download.
Four roles, from least to most access:
- Member — a regular account. Chat, browse, manage their own passkeys.
- Moderator — can open Admin, see the user list, and moderate chat.
- Admin — everything above plus invite users, edit names, change member/moderator roles, and suspend.
- Super Admin — everything, always (the matrix row is locked on). Only Super Admins can grant or revoke Admin, delete users, or edit the permission matrix.
The eight permissions: admin.access, users.view, users.invite, users.edit, users.roles, users.delete, perms.edit, chat.moderate. Built-in safety: nobody can change their own role, suspend themselves, or delete themselves; only a Super Admin can touch another admin; and the founding Super Admin can never be demoted or deleted.
- ⌘ Space — Spotlight. Type a few letters, arrow keys + Enter to launch.
- Esc — closes menus, Spotlight, and Control Center.
- Double-click a title bar to zoom a window.
- Right-click the desktop → change wallpaper; right-click GCM26 → open in a new tab.
- Aperture menu → Sleep for the world's most dramatic screensaver; any key wakes it.
- On phones: one tap opens icons, windows open near-fullscreen, the dock scrolls sideways, and the widget stack keeps weather + calendar + reminders.
- Your theme, wallpaper, brightness, and chat handle are remembered per device.
Scan any card to open it on your phone — or just click.
