So meetup have now purged 129,570 "frozen" groups  from their system. They now have 58,915 groups, although some of those are still what they refer to as "inactive" .
Personally I think it's a shame they've gone this route, as now a new group can't even start without an organiser to pay up front. At $19/month that's quite an amount for what is mostly a mailing service.
I note that there are now only 50 Perl groups registered, although only Franfurt is active in Europe
 frozen = 5 or less members and no organiser.
 inactive = 6 or more members and no organiser.
