In this one chat room i used to hang out in, the mic was moderated. IF there wasnt a mod in the room.. we would assign one.. When you want the mic, you post a T. When it your turn to talk, you get the mic for 2 minutes, then whoever is next in line gets the mic. I worked out pretty well, because it kept people from hogging the mic. A few night ago in the Bible study room some girl wanted the mic and nobody would give her a chance to talk
