"whats the minimum number of players you need to participate weekly in order to ensure enough money?"

We'll have enough each week to have the $60 towards the WSOP event. The more that play each week just means more prize money to be kept by the winners.

"What happens if we fall short of that goal?"

We'll worry about that if it happens. I don't think it will.

"What happens if a weekly winner fails to fork over his/her share of the entry fee?"

If I do not receive the winners weekly share after two weeks then they will no longer be allowed to play. I also don't think that will happen as we are all members. Andy - Las Vegas
