If you care to be Organizer for this group, it can easily be structured
to be free. Stephen, through his Group(Happy
<http://nightlife....; Meetup group, said this group can
just be made a subgroup. Since he is already paying the fee, the
organizer would just need to do scheduling.
Further, you could change things a bit. Not have as many meetings, or
have someone help you.
Please let me know if you are interested.
