I was going to type this, but then erased is as it was getting too complicated, but I blame Katies as she got my "teacher" thinking juices flowing . . .
How about 12 mods. Each month two mods are active, 1 named and 1 anonymous. Each of the twelve will "serve" two months out of the year, with one month being names and one month being anonymous. In some instances it could be valuable if there was need for a good cop/bad cop scenario that needed to be played out . . . ie. such as dealing with middle school students!! Some students respond well to me, other respond well to my peers. Either way, we solve the issues as a team of teachers. Sometimes I'm the bad guy, sometimes I'm the good guy!
Of course, I don't think there needs to be "that much" moderation, so maybe my idea is just that. Remember, I don't answer the questions, I just ask them!!
