EDIT: I believe Mods are all about replacing the original warcraft iii folder with an edited one, which is doable with any mpq extractor. You'll need someone who knows the ins and outs of the wc3 data folder. If this is wrong someone should inform me, but I believe there is little need to program unless you are replacing the .j files with your own code, which shouldn't be needed. Hope to work with you guys sometime.
