The list as Pete has written sounds like a good list. Of course, that gives you a thirteenth slot. Dawezy, perhaps? I mean, face it, he's all about having fun and being superior. He'd be perfect. Also, what about S or Merlin? (Does it really matter? They're admin; I suppose they can come in whenever they want.)

Hrm... oh well. You guys will get it figured out.
