It's your computer

Because even my computer does weird stuff with cookies. I'll be using the 'www'-less domain name of the Oddworld Forums to browse as a guest, and for some reason, it will send the cookie to the browser than I am browsing using the 'www'-full domain. Yet I will still be a guest, just the user Alcar is online
Which defeats my original purpose of staying logged out to browse.
