I use vBulletin to manage user accounts on my website. When users are browsing the rest of the site, I use this login information to control access to each part of the site, determine who sees ads, etc. I would like to use this userdata to automatically login users so they can comment without filling out a form.
Where can I get information on how the Movable Type authentication system works? If someone here knows how to do this, I would be happy to pay you for your time.
Kind Regards,
David
