Can one simply create an arbitrary community on any lemmy instance? I wonder how lemmy handles multiple communities of the same name, across multiple instances.
They’re separate but you can connect to communities across instances. I would recommend posting to [email protected] to give it some attention so others are aware it exists.
Sorry, connecting might be a bad way to explaining it. You can access communities on other Lemmy instances (as long as they’re federated together, which they probably are).
