On the half hour, there is a collection pot. Don't know how it works in the no limit games, but in the limit games if the pot is at least 10 small bets, it's a collection pot and the winner of the pot pays collection ($12/player in the 60-120, $13/player in the 100-200) for everyone who was dealt in. If you weren't dealt in, or declared yourself "out" of collection, you pay only for yourself.
