Maybe midwest.social would be a good fit? They're a US instance, so there shouldn't be any legal issues with FossCAD stuff there. They've also got a Socialist Rifle Association community already, so it seems that gun communities aren't unwelcome.

I connected the hack.liberty.organization admin and theyre okay with hosting it on their c/Guns

Looks like kbin blocks hackliberty. I'm assuming that at least a few others do too, due to the conspiracy theorist bent of hackliberty. In any case, midwest.social is significantly larger, and you'd have better reach there.

That might be a better fit. The conspiracy stuff was very off putting once I saw it.

Cool cool. Ping me once you get it set up? I'm not directly involved in any FossCAD stuff, but I'm interested in seeing more firearms content in general on the threadiverse.

Can do. Likely a weekend activity though. Ill have to learn a bit since I’ve never opened a community before.

I’d also appreciate a ping
