I hate to say it since I'm more of an anarchist--however, I think a flat amount of dues should be levied across the board. With that said; Lord help anyone that abuses the pot of money.. so I would actually suggest we have a treasurer who will provide accounting for us about what is being done with the dues and what dues have been collected. I've been a part of a guild (CoS) that abused such a system, the use of a treasurer should suffice to alieviate any concern of abuse of trust.

The treasurer could give us updates during meetings, that I feel should be held regularly, even if it is just for the treasurer to update everyone. This is how real clubs do it, this is how we should do it if we want to succeed with awesome turnout and participation.
