I did try Meetup. Even had a group of 24 members. Of course, only 1 other person actually showed up...
Everyone else, when I asked, just wanted to use Discord, and didn't realize what "In Person Gaming Group" meant. Oh, and can they game starting at 10 on weeknights instead of noonish on weekends? Oh, and can we just play board games instead of RPGs? Of course, they didn't actually communicate any of that until I started asking for feedback after 4 sessions.
Sadly, the one guy who did show up to every session moved away.
So after a year, I shut it down.
Honestly, what's the point of joining a gaming group if they aren't going to participate? One person who joined lived down in San Diego area... wtf???
