I organized a Meetup, and started to get folks joining the group. Every time I went to welcome a new member, I would get an error message indicating that I was not authorized to send messages to group members. I started getting messages for 'Joe'. My name is Dean. Somehow they got the wires crossed, and I was not able to organize meetings, reply to questions, or use any other organizer functions. I tried calling a customer service number that I found on the internet. It was a recording directing everyone to the website/email support. They do not answer emails directly, but instead send you a list of FAQs as answers. I had my credit card company reverse the charges and disbanded the group.
