 `/eqnotify` lets raiders subscribe to phone notifications for the raid targets they care about. It watches the batphone channel and, for each subscriber whose keyword tags match the batphone (buff / last-hour RTE calls are filtered out), pushes an alert to their phone. Alerts are only delivered to subscribers who **currently hold the Raider role**, so anyone who goes inactive or leaves stops receiving them automatically.
 
 - **Delivery channels**: **WirePusher** (free, Android-only) or **Telegram** (iOS/Android/desktop). Telegram delivery requires `TELEGRAM_BOT_TOKEN`; if unset, only WirePusher is offered.
-- **Getting your ID**: WirePusher users use their device ID from the app. Telegram users start a chat with the guild's EQNotify bot and get their numeric chat ID (e.g. from [@userinfobot](https://t.me/userinfobot)).
+- **Getting your ID**: WirePusher users use their device ID from the app. Telegram users must **first open the guild's EQNotify bot and send it a message (e.g. `/start`)** — a Telegram bot cannot message a user who hasn't contacted it, so sends fail with `chat not found` until this is done — then register with their numeric chat ID (e.g. from [@userinfobot](https://t.me/userinfobot)).
 - **Subcommands**:
   - `/eqnotify register <type> <id>` — sign yourself up (self-service).
   - `/eqnotify unregister` — remove yourself.
   - `/eqnotify add-tag <tag>` / `remove-tag <tag>` / `list-tags` / `clear-tags` — manage your keywords (use `all` to be notified for every batphone).
   - `/eqnotify test` — send yourself a test alert to verify delivery.
   - `/eqnotify add-user <member> <type> <id>` / `remove-user <member>` — Officer/Mod/Knight tools to enroll or remove others.
+  - `/eqnotify list-users` — Officer/Mod/Knight tool listing everyone registered, their delivery channel, current Raider status, and tag count.
