Okay, so you now have a choice of skins. They're just random because the server was down when I was adding them so I couldn't preview them but I think they're all pretty cool.

To change your skin:

+click on "Profile" up the top of the page
+scroll down till you reach the "Preferences" section
+where it says "Board Style" is where you change the skin
+It's currently set on "Acid" so just select another skin from the list.
+When you're done just hit submit at the bottom of the page

Any problems just let me know.
