In a restricted forum currently any moderator is responsible and able to approve new users.
Please add an option to select a group of users as user administrators.
Only these users shoud be
- messaged about pending approvals (A)
- allowed to show email-addresses (B)
- able to see and approve membership requests (C)
At least in our case, (A+B) is more important compared to (C).
Implementation wise, it might be cheaper to restrict user administration to the intersection of this group and moderators.
