Looking for a developer to build a bridge that updates Zencart/vBulletin both ways and bridges logon:
Bridge must integrate the following:
* registration with prompt to enter additional customer information on first visit to Zencart
* password recovery and algorithm
* any changes on user name, password, or email at Zencart or vBulletin must update the other
* Session should be shared by the two
Zencart should use the vBulletin database for username, userid, password, email, but otherwise has separate tables.
