We run the club so that events are typically funded by event payment fees.  And our advertising pays for other fees (such as website fees, meetup.com fees, providing bottled water, donations to museums, etc).  Although we appreciate anyone's interest in donating, we really don't accept donations.
The best way to help "Fund the Fun" is to shop with our advertisers.  Clicking our ad links before you buy will help us generate revenue for the group.  And for that, we say THANKS!!
