I want to make Integration between PostNuke V762 and VBulletin V3.5.4 just Integrate the users to be One registration system for both PN/VB - One login for both systems. Users don't need to login twice for PN/VB - If user changes the password in PostNuke it automatically gets updated for VB also and vice-versa. All of them are already installed. Postnuke no users. VBullten has users.
