I just started using the LaTeX community (!tex@lemmy.sdfeu.org). 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 !tex@lemmy.sdfeu.org, I guess it’d still be like a ghost node because the post would have nowhere to go on the hosting node.
the tex community is working on voyager
I’m not sure what that is. vger.social and voyager.lemmy.ml don’t seem to have anything relevant. But I found !tex_typesetting@lemmy.sdf.org.
Your client would make a difference. What you are probably seeing is the mirrored version of !tex@lemmy.sdfeu.org on lemm.ee. You cannot possibly be interacting with a non-existent community. If I post to https://linkage.ds8.zone/c/tex@lemmy.sdfeu.org, then I don’t suppose you would see it on https://lemm.ee/c/tex@lemmy.sdfeu.org.
(edit) just saw your test msg. Well, that’s interesting. Even though !tex@lemmy.sdfeu.org no longer exists, it seems the mirrored versions of it can still collaborate. I’m not sure how that works.
