Tales of Maj'Eyal and T-Engine4

First a quote from Darkgod:
"I'll ask people that contribute to release copyright to me, or to give me right to relicense the code as I see fit (you can add a "as long as its opensource" if you wish, it'll never change" http://forums.te4.org/viewtopic.php?f=36&t=21351

Now, here are some ways you can contribute to the game even without knowing how to program:

• Music! Help us find more music released under creative commons that is usable in the game.
