So in regards to server groups is there a way I can remove server groups from a client all at once or do I have to take each server group off them individually?
You can select multiple people in the server group list. (As far as i know)
He’s not asking for multiple people but for multiple permissions.
You can always do it by serverquery or by the set server group box on the client where you can tick/untick all the permissions you want if the client is online.
If the client is offline you can do it by the server groups page (where you modify them) and remove it from the lists on the right, there you can search but not remove from many all at a time.
Another alternative is yatqa (so serverquery)
