Ive had experiences with meetup too! First they charge a lot to start a group but also they took away all my members when I wanted to charge monthly fees and charge my members the monthly fee only if they decided to attend a meetup, but they changed that! Now my pending members were all deleted and I would have to contact all them one by one! It's horrible only left with less than 100 members when I had over 1000! Meetup really does not want us to have members! They are greedy! Hopefully they will change it back to where it was or I may be leaving meetup for something better!
