Sure, why not. I should be available this weekend. Now I still have exams. But yes, I'm interested in helping you. But what do you exactly mean by documents?
If you can help me setting me on course by telling what you need, I can try to provide you with the correct information. I think the most important part are the units because after all, TW is about war. More people pay attention to the military aspect of the game. But even if you want economic or geographical information or whatever, please let me know.
