When you choose not to use cookies, your username and password have to be sent from page to page some other way (I'm not exactly sure how, maybe it's that big long s variable that gets sent every time). The chat page must only take the cookies for logon (it doesn't get passed that s variable?), so you have to sign in if you don't have a cookie.

I did a test and without cookies, the s variable is set to a very long string of numbers and letters. With cookies, the s variable was set to nothing every time. I'm assuming vBulletin has a function that encrypts and decrypts the username and password, so Brandon should be able to pass the s variable to the chat so you don't have to keep logging in.
