Everytime somebody registers to be an affiliate one user is created in Joomla but two accounts are created in Affiliate Tracker. I have been unable to find the reason for this. One account is always automatically approved after joomla user activation but duplicate second AT account is unapproved. How can I prevent AT from creating two identical accounts from one joomla user registration?

Also, how does the system know when somebody in one city signs up somebody in another city? I don't see any field for the downline person to enter the upline affiliates ID#. How can the system know who the new downline is if the new downline does not enter any code at the time of self-registration?
