I have a Symfony 1.2 Project which needs a forum implementation.A sfGuardPlugin with the associated tables are used for the authetication process by this project. I'd like to install a vBulletin forum but I need it take the users provided by the sfGuard tables as well as the forum registration and authentication mechanisms. In brief, I need a unique point of access for both systems (Symfony and vBulletin), like a Single Sign On, in which users can login and register in both enviroments at the same time and in a transparent way for them.
As an experienced vbulletin plugin developer I think I would be well suited to do this for you. I've done similar projects for PHPBB based systems in the past as well. See PM for a bit more info.
