https://lemmyrs.org/c/rust@kbin.social works for me. I believe there is a generic way to link to communities that works for all sites… but I don’t know how. I know the format is something like !rust@kbin.social but nothing seems to convert to a link etc
Edit: perhaps just relative links? /c/rust@kbin.social
I’d be happy to take an invite code off of someone’s hands (and then share the friendship some more!) :)
