Reddit has subreddits. What does Lemmy go with?
My personal vote is for lemmings!
Edit: I am personally leaning towards Sublemmy now. It retains the context of being a forum under the general sphere of Lemmy and the connection to Reddit lets people know immediately what Lemmy is about. Thanks to @[email protected] for the comment!
Some called it “sub” or “subs” for short on reddit. Why not just keep the same one without the “reddit” word. Lemmy sub -> sub. No need to invent some random words for every instance.
