Fight Club-Advice or Ideas?

you should have the members of the fight club sign a waiver with the rules and expectations on it so if someone wants to sue you; your not liable. Also think of having them wear gloves because no one wants a broken wrist. Make some type of rule that you have to fight a certain amount of times per month and people are allowed to challenge others. The person being challenged can only turn down two challenges per month or something. New members have to fight their fist meeting or night.
