Strange only if you were not aware that you had a complimentary Membership for a year.
Many customers who purchased video tutorials under the old system were given complimentary Memberships for a year. These expire on November 29 2016
I will ask the tech guys to blend your forum and Membership accounts which use the same registered email but have different usernames. You site registration will them become the same as the Membership allowing a single login to both the main site & the Forum
