How about just making a subscription fee? I know that would keep away some members, but maybe its for the best.
Maybe only members in the DL/UL club should pay, as they are the ones getting the biggest benefit. It would also not drive away new members as they could experience the site for free and once they discover how special it is they wouldn't think twice about paying.
Just a few quick random thoughts......but I would be happy to donate something if thats what it comes too.
