Admin

Approving sign-ups, spending, and who may use the server's key.

Admin is only there for accounts marked as administrators. It's in the account menu, top right.

Spending
What each person's use of the AI has cost this month, and how many calls. Every person has a monthly allowance; past it, the assistant stops for them until next month.
New accounts wait for approval
Ticked, new sign-ups wait until an admin presses Let them in. Switching it on doesn't lock out anyone already here.
Suspend
Stops someone signing in. Nothing of theirs is deleted.
Make admin
The last admin can't stand down, or nobody could get back in here.
Uses your key
Whether a space may use the server's AI. Untick it and that space's assistant, photo reading and tag suggestions go quiet. Everything else carries on working.
