We are adding vb forums to our custom built site which already has a login system, members page, etc. Is there any documentation or does anyone have any suggestions on how to integrate vb forums so that users do not have to login and register twice (once for our main site and once for our forums)? We would like to keep our main site registration and login form as the only means to login. The vb access would just be generated based off of the main site login.
