Almost 1.2k of my group members were removed by Meetup.com, after I stopped charging member fees. I had to stop charging, because Meetup.com put all the unpaid members in trial... pending removal... mode. So basically, they just took my money for 6 months and took away more than 90% of my members. Now, I have no way to contact many of my friends. I emailed them and tweeted at them... So far, no response. :(
