See the other message I have written - you should always recommend search. The URL only works if someone has already searched for that community. If you're on a big instance, that's almost always true, but on a smaller instance it often isn't.

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: !juggling@lemmy.world
