SQL data created upon registration

[h_kakashi]

I managed to figure out how to do the registration page using the datamanager class, my only question now concerns vbulletin's cookie/session authentication.

How would I be able to create a universal session/cookie so that if a user logs into my cms/vbulletin, they would be logged into both the cms and the forums. I've already created the actual code for the login check (username and password sql query), its only a matter of setting the right cookie, using php's setcookie function... im not sure how tricky this would be to make sure it works with the 'remember me' option on/off.

Can anyone guide me?
