I just started using the LaTeX community ([email protected]). Sad to see it go.
update
Just noticed it’s back up, but there are no communities. That’s bizarre. So if someone not on lemmy.sdfeu.org were to post to [email protected], I guess it’d still be like a ghost node because the post would have nowhere to go on the hosting node.
I’m not sure what that is. vger.social and voyager.lemmy.ml don’t seem to have anything relevant. But I found [email protected].
