With the new forums, I can change which theme you can see default, but the theme gets cached at login, so if you haven't logged out/in since yesterday, you won't see it. You can change this manually just logging in and out real fast, or, one of the new features we are leaving available is to be able to swap themes manually based on your own preference. This can be found at the bottom of any page. Currently there are two complete themes, the generic SOK one, and the Winter one. You can change to winter yourself. If you don't like it, you can swap back to the SOK one. You might see a Dark Knight's one that Zesh has been playing with, I am not sure its 100% complete yet, but you can also try that out.

In the future, any themes we build will be available all year long. If you love halloween, you can just leave that one running. If I do any new April Fool's ones you like, you can keep those too.
