I can empathize with Rick. We have weekly sessions, but never exceed 12 people. Which means, that when we have more, we just add another night to the week for music. We are pretty ridgid about going in the circle, with people accepting, or declining the turn as the mood strikes them, but everyone has opportunity with each revolution. People who don't play nice and abide by this are not invited back. This is not being elite, its called survival. The whole point is to have fun, right?
