How about JUST ONE rebuy. Which must be taken before the break. All or nothing is a bit harsh, so one rebuy? You dont have to use it. LFCEoin in his first ever game with one $5 buy in won the thing outright it is possible.
I agree too many people think one rebuy and an add on is too much for a social game.
I will also see about getting more places paid, but this might be out of my hands.
Any other suggestions? Is the day/time OK? They can go on a bit I think certainly with the add on at the break I think without that they may finish quicker. I assume staying at FullTilt is OK with everyone?
