BIG BAD WOLF: An interesting idea! A trading system of sorts would need to be set up. Also, when one pays for his membership you could be given some Brains. Offering them as a tournament prize would be something you could do with them. Fencer could still give them out for referals.

Brain's value would depend on how many Brains it would take to turn them in to get a year's membership and how hard they are to acquire. I suppose the outright buying of Brains could be figure into it too. That'd certainly help orginize tournaments for when the prize is a membership. It'd really make it easy for the tournament creator to have different prize levels during one tournament too.
