What did I do to my templates?

[Kran]

I've been playing around with templates lately, and I did something to my templates last night, but I'm not sure which one I edited to make it look like this.

Here's what you get when you go to index.php


Here's what you get when you click on General


So, I ask the question again... What template did I edit to do that to General?

And just to clear a couple of questions: Yes, the layout is inspired by Something Awful and 2, you have to remember that I'm only 14, and that I have some pretty stupid friends with pretty stupid user names
