How do usernames work? If someone has a username on one instance, can someone else register the username on another instance? If so, how are they distinguished?
Yes, you can have same usernames on different instances.
The full username is always @user@address.
So I'm @barbarian@sh.itjust.works. There's also a @barbarian@lemmy.ml (that's also me, I stopped using it to help with server load, but ignore that part :P). Servers and people can distinguish between the two users because it always includes where the user is from.
