@@ -2,6 +2,7 @@ A collection of miscellaneous mods for minetest providing "utility" functonality
 
 Each mod in the pack is effectively independent, with minimal or no dependencies (including on any assumed underlying game) and they can be enabled/disabled individually.  Mods are distributed as a single pack because they have a single shared maintenance/release cycle.
 
+- `szutil_admin`: Alternative to the "admin" command that lists moderation team members.
 - `szutil_chatsocket`: Expose in-game chat stream as a unix-domain socket for arbitrary chat integrations.
 - `szutil_chatsounds`: Configurable beep notifications for in-game chat.
 - `szutil_clocksync`: Synchronize in-game clock smoothly with real-time clock so users can log in at predictable times of day.
