Their main community

It looks like this is !main@sh.itjust.works

Most Threadiverse instances have some sort of “instance” community — personally, I think that it should be be a default on instances so that we have a single standardized name.

On lemmy.today, there’s !lemmytoday@lemmy.today to act as an “unregulated” community and !announcements@lemmy.today, where posting is restricted to the admins, so that official announcements don’t get drowned out. I think that that’s not a bad approach.
