How does this system handle unique usernames? It seems like a flaw in the system if other people can take unique-seeming usernames on other servers. Will this network be overrun with impersonators?
@mathowie I was wondering the same thing. I figured I could transfer my account or re-use it on another instances. However I was able to register with the same email + name.
