Just curious how folks here work these in their games. I currently allow one Rebuy (buy in amount for same starting stack) if you've been felted. I allow one add on (buy in amount for same starting stack) at anytime, noting that if someone is stupid enough to do that when that equals 2 big bets, well that's your prerogative. I know some folks have hard cut offs for the timing or do add ons for a lesser amount than the buyin, etc. etc. Just wanted to see what other people were doing and why.
