Long answer: you can, but there won't be any real effect.
Short explanation: you've got moderators, and you've got admins. That's it. Moderators have too little power to be effective in a day to day administrative capacity, admins have too much.
Long explanation: if you want to call moderators super uber leet clone commando captains, that's your prerogative. If you want to call certain members super uber leet clone commando sergeants, you can do that. They just won't have any real power. Permalink
