Heavysheep is running a tutorial that teaches you how to "Mess with MSN Messenger." It shows you how to use Mess patch to remove all sorts of things from MSN Messenger like the MSN or Passport logos, the MSN Search box, almost any button, and yes, the ads. You can also do things like move the tabs the the right side of the window and get rid of useless warning messages. Guaranteed to piss off Microsoft.
