"Your names in the "Address Book" for billing are not the same as your account name. You only have to change your account name. When you add a new game to your account it counts as an update, which would trigger the the forums to re-check your account name."
If that is supposed to be the "account name" why on earth are the fields listed as "first name" & "last name". It makes no sense and it needs to change.
