Once a month, usually the last Tuesday of each month, Battleground has an informal show-up-and-paint night. It's nice, because people can trade painting tips, suggestions and just chat in general.
This would be the first one I've remembered since July. Apparently, people on Facebook know about this sort of thing, but the forum is neglected and unloved.
From the Google calendar:
"Come down to Battleground in Plainville to hang out, eat some pizza, paint some models, watch / talk about movies and TV, and have fun! New and experienced painters are welcome and encouraged to join! We've certainly got plenty of projects to work on, and I'm sure you do too. Last month we had a bunch of people come out and had an awesome time. I'm looking forward to this next one."
