Some cookie issues

[Meltingfire]

Hey!

I just installed vBulletin so im kind of a newbie...

Im doing a Statistics site DirectConnect (www.DCStats.net) and its something like mIRC-stats but this works in realtime....

because everyuser in the DC hub that is logged, can create an "webaccount" in DCStats. that they can fill information about them like name, e-mail, upload a picture/avatar etc... i also wanted them to be able to use a forum as well...
But i only want the users from the DC hub to register at the forum, i disabled the forums "register.php" page... (and also the change profile page)

So now they login to there webaccount in DCStats and then "transfer" there user (like name, e-mail etc) to the forum...

I had to work a bit to get this working but after a while i realised that when i create the user in the vBulletin DataBase (mySQL) i have to create it in 2 places, in "user" and "userfield" tables, or he/she wont be visible in the members list.

When i create the users i have my "standard settings" for them like "able to recieve pm", "e-mail hidden" etc...

My problem is this:
When a user browses away from the forum, to then return, he is logged out.. so my first thought was, i have to use cookies instead of session, so i changed "nosessionhash" in "user" table to 1, to make it cookie-browsing. i also set the cookietime to 1day

But the users still get logged out...
i found in the options for user where to set "log me in when i return to forum (cookie)" but i dont know WHERE in WHICH table to look for that... can somebody tell me? i have really search the vBulletin DB and found nothing

(For you that dont know what DC is, its DirectConnect, a peer2peer download/upload program.)
