So I was signing up for something earlier and instead of typing my email address I typed my nickname @gmail (which has never been my email address because it's a very identifying nickname). And the service I was trying to sign up with didn't have any way for me to contact them and say "hey, I'm stupid, that wasn't my address". And now it won't let me sign up again with same name/dob but correct address. *cry*
ah man that sucks, sorry to hear :(
