Chuck, there is no integration, classifieds runs on its own http://greekads.com/classifieds/index.php
To restate the problem
I logged in ok as the administrator, I changed the email address (lets call this email address2, later I signed up as a different user, not as Admin, and gave the email address 2.
This caused the problem. Admin does not have t he status of administration.
My email is firstname.lastname@example.org
