Hello, I am a new member to this site and the game itself, but I can't believe I never knew about this game until just recently, lol. That probably sounds sad to most people here, but it is true. Also, I have been recently looking through mods, models, and stuff relating to custom work. I am currently attempting to make a custom race through the world editor, but the problem I am having seems to be that the system I want to implement is using vJass I think and does not exactly explain how to add a new race through the system, but states that it is easy. I will only post the link and also ask that other people respect the original author's work and wishes.
