Meetup is going through a transition and things are not good.
I have been an organizer or assistant organizer for multiple Meetup.com groups over the past five years. It's a great way to meet new people who have similar interests, it's usually a safe way to meet new friends, and it can offer new experiences at events to teach you a new skill.
That said, Meetup was sold in late 2017 and they have been undergoing a re-programming of the website and it has been a disaster. As an organizer, I find it harder and harder each day to use either the website or the mobile app because links are broken, tools I used to use are no longer working or missing, and members of my group are being dropped from event without their permission.
Meetup corporate has changed their phone number and emails to their team are bouncing back unanswered. The few people who used to be there to help with web problems are gone. I'm still paying almost $200 a year for the ability to use Meetup with my group, but getting more frustrated each week as more problems arise.
It's not that we organizers cannot learn their new system. It's that the new system does not work as promised. If anyone is checking reviews and thinking of becoming an organizer and using Meetup my advise would be to wait 4-6 months and not sign up right now. You will pull your hair out waiting for things to be fixed. If I didn't have so many events already on the calendar I would walk away from Meetup today.
Update 2/28/18. Website is still not usable. I and my members are fed-up with the lack of support from Meetup management. This week I told Meetup I will not renew when my group comes up for the next payment.
