Congratulations, you have made your way to the rest of the puzzle. Let me explain how this works. (As stolen from relpats-eht) As you discover more and more solutions, what you type into the address bar will get longer and longer. By which I mean, if the answer to this page was "four", you would head to uxux.org/four/. At that page, you'd find another clue/puzzle. If the answer to that clue was "score" you'd go to uxux.org/four/score. And so on. Got it?
Oh, and please don't try to brute force this. It won't work and my hosting package won't be able to handle it. Thanks... and enjoy.
