I know this has been suggested before but
New ranks, owners can give different ranks to people
Owner: same, can do everything
Trusted staff: can add Jr staff and works as staff, can change world settings
Staff: can build and moderate, cannot change world settings
Jr staff: can build with other staff can use staff teleporters and buttons, can not moderate
Builder: can build but nothing else
Moderator: can kick
This would come with a new board: ot shows you everyone with permissions to do stuff and what they can do
