V4.1.x Enhancing vBulletin share...

[shri +]

I'm keen to enhance the vBulletin usershare module to automatically register (if not registered) and log the user in, if they're already logged into vbulletin. I'd like to do this to make sure the user does not have to login twice and also to take care of multiple user groups we have in vB. (The user share needs a second login .. and only seems to work with one user group).

I've gotten to the point where I can detect that there is valid vb session from within init.php

        chdir("/site/2010/beta/forum");
        include_once("global.php");
        chdir($cwd);
        global $vbulletin;
        $vbuser = $vbulletin->userinfo;

How would I go about forcing the 68classifieds session, registration and login?

Happy to pay for this if needed...
