There's one on sh.itjust.works which I would use; it only has 100-200 subscribers though. There's also one on lemmy.world, but it doesn't have any posts, and one on lemmy.ml, but it's lemmy.ml.
If you put the entire url into the community search, I'll show no results at first, but either after about 5 seconds, or after clicking next, it should show up for you to subscribe to from whichever instance you're on.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !twosentencehorror@sh.itjust.works
