Our first meetup (December 20th) went wonderfully - we had 17 attendees, got manifold usernames/discords from most of them, and had a genuinely fun time. I believe there were 5 new users.
I got distracted over the holidays, so our second meetup (yesterday) was poorly advertised and got much lower attendance. I'm about to set up a weekly series though to both make up for the missed week, and to help make it more of a 'thing' (as David suggests below).
Stefanie has also been a wonderful help!
