I'm trying to view Apple communities to look at an iPad case thread I read a few months back, but apple.com keeps requiring me to sign in twice and then select a username to even view community topics. When I put in a username for my Apple ID, I get this error message, "An account utilizing this email address already exists. Only one account per email address is allowed on Apple Support Communities." The bottom of the page say it's on Create Apple ID when I already have one and logged in. I didn't ask to create a new account, but it pigeonholes me here and I can't get back to that support thread. When I look at the Manage My Apple ID page, it shows my email address is my merged ID and is only effective on iTunes and iChat. I have no option to add or create a username on my Apple ID account. Am I not allowed to create a username for their communities on one Apple ID? I don't want multiples. Anyone have a solution or insight for this?
