All Set Option things should be configurable in Admin Panel:

Set Yes/No option for members to be allowed to join X usergroup via User CP
Set Usergroup Leader (or Leaders) to approve members/add any member/remove members via ModPanel
Set option to "move/switch user and automatically remove user from old usergroup when joining the new one" for example switching from Allies to Axis usergroups - should be able to set which usergroups are linked... like if player is in usergroup Civilian (default) and gets admin switched to Allies then don't remove Civilian or any other usergroup memberships... but if player was Axis and is moved to Allies it would auto-remove them from Allies (only)

I could think of some more ideas to implement but the above stuff would be the base ideas I would want... Thanks
