This and the other resources thread should be stickied.
I've been sifting through the small number of game mods, and through the even-fricking-less modding info, and dug up this little gem, which should be of interest to anyone who wants to mod the game.
Sim and Subsim Creation - by Particle Systems http://www.mediafire.com/?u65bgoobot41taj to the best of my knowledge, it's the only real source of info for modding the game. I'm going to try to use it to create a multiplayer map with some significantly bigger fish in it: a few capital ships, and some fighters. My goal is to create a small carrier battle.
