 - **Recovery codes and activity log**: Settings -> Recovery codes makes 8 one-time codes; if you lose every device, the sign-in page's "Use an invite or recovery code" adds a new passkey with one (codes are stored only as hashes). Admins see an **Activity** list in Settings (sign-ins, failed sign-ins, passkeys added or removed, invites, recovery code use, people changes, backups); it is `/data/audit.log` and never contains codes or passwords.
 - **File version history**: on any Seafile file, "Version history" lists earlier versions with who and when, and can download or restore one (restoring keeps the current version in the history). This uses Seafile's history API and has not been tried against a live Seafile server yet.
 - **Code layout**: `public/` holds one script per feature (`tasks.js`, `calendar.js`, `music.js`, `player.js`, `files.js`, `settings.js`, ...). They are plain scripts that share one global scope and load in the order listed in `index.html` (`boot.js` last); the versioned `?v=` addresses and the cache version are computed from every file in `public/`.
-- **Podcast** and **Podcast Admin**: launchers that open `PODCAST_URL` (a home-network address) and `VERSE_URL` in their own tabs.
+- **Podcast** opens `PODCAST_URL` (a home-network address) in its own tab. **Podcast Admin** is no longer a menu entry: it is a built-in link on the **Links** page (opens `VERSE_URL` in a new tab, cannot be edited or deleted) for people who have the Podcast Admin permission in Settings -> People; the old `#/verse` address goes to Links.
 - **Office**: embeds onlyoffice.necloud.us in a frame, with an "open in new tab" fallback if it blocks framing.
 - **Mail**: several mail accounts per person in one place: **Gmail**, **iCloud Mail** and (optionally) **Outlook.com** (personal). Folders with unread counts, message list with search, reader, compose with attachments (up to about 3 MB) and a From choice, reply, reply all, forward, archive, delete, flag, mark unread, an unread badge on the Mail tab (all accounts added up) and a Home card with the latest unread across accounts. Each person adds their own accounts (Mail tab, or Settings -> Mail -> Add an account); everything is private to them and stored encrypted in their own folder.
   - **Gmail and iCloud** use IMAP/SMTP with an **app password**, so there is nothing to set up on the server. Gmail: turn on 2-Step Verification, then make an app password at myaccount.google.com/apppasswords. iCloud: appleid.apple.com -> Sign-In and Security -> App-Specific Passwords. The password is checked with the provider before it is saved, and wrong ones are explained in plain words. iCloud does not keep a copy of mail sent over SMTP, so NE Hub files one in Sent itself (not yet confirmed against a real iCloud account).
