Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
So, suddenly PO is requesting a password when I try to enter any servers, which it never did before. As I never registered a password, I think somebody else might have registered my name. Help?
Yeah, someone registered your name. There is no one to blame but yourself for not registering your nick. Let this also be a lesson to everyone else reading this to register your names.
Alt check on the user "Plaid" doesn't show anyone other than your nick, meaning I cannot track down who registered your name. Might as well make a new nick now and register it.
