Hey there,
Upon attempt to login into forum, I get following error:
email address you entered is already in use, but is bound to another account. Please contact customer service.
I don’t experience any problems with access to other services like AnswerHub or GitHub. What may be causing this?
Hey EF,
Sorry you’re having trouble logging in. Please contact accounts@epicgames.com and they can assist you.
EF, can you please try to login again to forums again (using e-mail and password)? We believe we have fixed problem in your case. It was a simple bug because your display name is 2 characters and forums expected 3 or more. Because of this bug, your account was failing to create on forums.
Let us know how it works out.
Guess I could have picked a longer username 
Anyway it’s working now. Thanks!
Glad to hear it! Thanks for reporting back that it worked.
