Possibly About Cookies.

[Fugler]

Hi. I was just starting to make a little addon for my forum and I was just wondering how you'd go about checking wether a user is logged in or not. I'm assuming the user is sent a cookie once he/she's logged in, but I don't know what the cookie would be called so I can't check if it's there or not. Unless I'm just completely wrong of course.

Also I'm guessing that the styles that the users choose are stored in a cookie also and it'd be great if I knew how to get this one too, but I don't

So if anyone can help me with these issues I'd be very greatful.

OK.. I think I got the first bit fathomed.. and I don't really need the second bit anymore..But now I'm wondering.. Does anyone know how to use the CSS for my styles on my forum on a non vBulletin page, cause I can't seem to find the CSS file or anything.
