What happens to the users of one instance when that instance is shut down or deleted? Searching for a url seems way too complicated. Can't one subscribe to a server or sub category on a server?

This I would really want it to work but it's much worse to me than forums even.

I use kbin too.

New to this feedverse or how you call it.

Why isn't there one login that can post on all platforms and I have to signup on each separately?

If there is, you're not making it obvious I guess.
