Help me log into Apple Support Communities please!

[jaardesign]

Hi, I am trying to log into the support forum on Apple's website but I can't. It is prompting me to create a username but I already have one!

I go to apple.com, click on 'Support', click on 'Communities'. Then it takes me to a page that has me sign into my apple id. I click 'Sign in' and it brings me back to the same page but says, "Please sign in again. For added security, we need to reconfirm your Apple ID.". So, I fill out the ID and password and click 'Sign in' again. Now comes the problem part, it then takes me to a page titled, "Pick a username". I already have a user name, but if I enter it into the username field, it tells me, "This username is already taken, please choose another. Another has been provided." But, when I enter in another Username, it tells me, "An account utilizing this email address already exists. Only one account per email address is allowed on Apple Support Communities.

I have tried multiple browsers, IE, Safari, Firefox, Chrome and it does the same in all.
