In the past two days I've been trying to create a community, but without success. I insert the name (with the allowed characters), the display name, and so on. But when I click on create a spinning wheel appears for a second or two, then goes back to create and nothing has happened. I created two communities previously (10 days ago or so) without problems.
I imagine it's just an effect of the current load for Lemmy.world, but wanted to ask just in case.
Community names are, by default, limited to 20 characters only. No errors or anything pop up when you exceed that, but you can ask your admins to extend the name limit.
