I agree with ER. There are alot of modders who started with nothing and are now capable of doing entire mods on their own. All that matters is motivation, time and a bit of logical thinking. When I read: "I want to help, but I don't have the skills." I tend to translate it to "I want to help, but I am too lazy." Those responses are not particularly encouraging as it tends to back up the idea that the modder is working overtime while the rest are relaxing on the couch with a sixpack.

So be a hero and help Adherbal with finishing Chivalry: Total War! It will be quite rewarding once you have helped creating something that will be played by hundreds of people and that will be no doubt the case with this mod.
