It's a special TOP skin someone made for CN. I forget how it works since I installed it well over a year ago.

Its an add on for firefox called stylish. You can install it and then download themes for all sorts of different web pages. I have ones installed for CN, facebook, youtube, etc. Its actually pretty cool. I run the TOP CN script myself because I like the dark colors I'd love to make on for IRON but I'm not that tech savvy.
