Username issue

Yeah, I am, but it keeps saying it doesn't recognize my email address...

So, you actually signed up using some different email address instead of the one you're using now.

Hey there...

Eris, you can't sign up because someone else already snatched up that handle, even though they actually changed their nickname just today.

Like, look at me—I used to be De Beers but I went ahead and switched my name to BlackRock, yet you'd still find yourself blocked from grabbing De Beers even if it looks totally available now.

So, yeah, that's basically why it's happening.
