Thanks for pointing me to that @Benjamin_D !
It looks like tokens can be set to be usable only once, and there’s a per-user limit. (So I could say, you can only invite 1 new user per day, for example.)
Is there a way to limit total growth? …a total limit across the site for the number of tokens generated per day— and zero should be a valid setting so I can effectively freeze new invitations.
The invite interface should say something nice like, “sorry there is a limit to the daily invitations and that has been reached for today” …or something making it clear that a) you have reached your per-day limit versus b) the site has reached it’s entire, all-users-combined, per-day limit.
