I had not logged into the boards for awhile (way before switch to SSO) and logged in with the email i knew to be my Ubuntu One acct. I thought it was my forum email as well. Apparently not, as it did not take me to my old account or username, but instead created a new one for me.
I know the username of my old account, not entirely sure of the email but i could list off several possibilities.
Is it possible to have this account diassociated and return to my old one? If so, what information do you need to know - i'll be happy to provide it in a PM.
All the best.
