i once said something pretty much the same, don't know it's fixed already but when you gave yourself a custom name (yeh lame to have yourself on your contacts but it's for testing) in the login you'd get the custom name instead of the e-mail, pretty hard to sign in that way.
I haven't been active here in ages.
If you're wondering who i am, read my reputations. I used to make plugins, skins and spam the IRC channels here back in the good old days before Windows Live.
