I autocrated a large event during that time, and my feelings on the
policy were so strong that I did not charge any site fee, so as not to
have to collect the "non-member tax." It gave the cook nightmares not to
have any reservations. I do not believe in a "pay to play" policy. I
believe that membership should be required of the corpora-mandateed
offices (which have legal existence in the real world) and that is all. 
Certainly not for participants, including fighters. If you sign your
waiver, it is enough.
