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.
This reaches the borders of my understanding of the fediverse :) You mean I could create it on Lemmy.ml for example? Would I need to create an account there? I'll explore, thank you for the suggestion.
Create an account on another instance (I suggest a smaller one, to spread the load)
Create a community using that account
Post or comment in that community with your main account
Use the newly created account to promote your main account to moderator in the community
Profit
A little convoluted, but I guess moving things off the big instances is good for the fediverse as a whole, because single instances only scale so far performance-wise. Don't worry about discoverability. It'll take a couple days, but it'll work out fine. You can boost discoverability by searching for your community from bigger instances. That'll kick of federation / synchronisation.
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.
