Conquest of the Horde

Well, I just recently got my Introduction accepted. So I decided to make a server account. But when I type in my Username and password (The one I log onto this site with) exactly it says "Your login information doesn't match a user on the forums. Please create an account on the forum and use the same username and email from there. Keep in mind that both the username and email are case-sensitive! They must match your forum account exactly." Perhaps I missed something on the Wiki?

EDIT: I just reread the question. Why on earth I asked about the realmlist I have no idea.

I don't think that the realmlist would have anything to do with it.

I would say wait a while then try again. Several other players are experiencing this problem.
