 ### How it works
 
 - Threads and posts are stored in `~/.tinyweb/forum.db` (separate from your search index)
-- Instances sync forum content over Reticulum every 5 minutes
+- Instances are discovered automatically via mesh announces — no manual setup needed
+- Sync is manual by default: click "sync now" on the forum page. Auto-sync every 5 minutes is optional (toggle on moderation page)
+- At scale, sync uses epidemic gossip: 20 random peers per cycle, converging globally within ~O(log N) cycles
 - Authors are identified by a short pseudonymous identity hash (no accounts, no sign-up)
-- Moderation is local: block authors, mute threads, keyword filters, and gossip block lists with peers
+- Auto-discovery can be disabled in the moderation page
+- Threads are auto-pruned after 30 days (configurable, or set to 0 to keep everything)
+- Moderation is local: block authors, mute threads, keyword filters, and gossip block lists with peers (auto-block after 3 peer reports)

 - **XSS escaping** — All user-supplied content is HTML-escaped before rendering
 - **Bookmark authentication** — The bookmarklet endpoint requires a secret token
 - **Identity file protection** — The Reticulum identity key is restricted to owner-only permissions (0600)
+- **Forum caveats** — See [tinyweb-forum Security](https://git.derickphan.com/lichenblankie/tinyweb-forum#security) for forum-specific risks (voluntary retractions, block gossip manipulation, no rate limiting)
