I still think combining forces for an accurate historical campaign would be a good idea. I could easily set up a Google- or Yahoo group to share missions, reference material etc.
It would only work if everyone agrees on the place & perios I guess?
... Not that it really matters, but I'm partial to the rolling hills of Reims.
There are other areas of the Front that don't change from 1917 to 1918. Basically anything East of Tahure and North of Arras is fairly constant.
Some links that help the historic approach:

That is some great info Gustang! I also like the terrain near Reims, perhaps near/east of Reims would be a good spot? I just have no clue if there was much activity there in 1918?
Another option would be around Douai. Lots of info on that part of the front I guess...
