For the sake of somewhat easier score tracking, I've opened my extremely alpha script for use here.

To set your game to upload, go to the frets directory and open fretsonfire.ini. Change the uploadurl value to
http://thnfrets.ath.cx/frets/ and change uploadscores to true if it isn't already. When you play a song, the game will upload all your highscores from that song.
Like I said, it's really alpha at this point, so sometimes it won't even record your scores, and sometimes it will record them under the wrong difficulty. It should do for now, though.
Also note that it's running from my home computer, so when it isn't on you won't be able to upload or view. Live with it
