Beside this one, I see there's also an Emacs community over at @emacs (tho apparently I'm still "subscribe pending" there, after several days). Any others out there?
I didn't see an #Emacs community on lemmy (maybe I didn't know how to look, or didn't look hard enough), but Emacs has always had a strong presence on various social media sites. Here's one for the Fediverse!...
