I've searched high and low on vbulletin.com and here and I've yet to find a definitive answer. This should really be part of an FAQ or something.
Personally, I'm using vBulletin on a private section of my site (
http://www.interpug.com) and I'd like to make it so the entire private section (/private) is password protected via vBulletin's user authentication. I don't use PHPNuke or any other scripts, I just want to integrate it with the rest of the site.
Any help would be appreciated.
