I like the idea of a rating system. Maybe we could start a list of what each person thinks are the best books for each region and people can add their ratings to them, like 1-10.
I also like the idea of preserving the forum's knowledge in an organized way. I am just a newbie to collecting but I would be willing to help edit if the work is done in english.
It might help to concentrate on doing "articles" on particular types of weapons or regions. They could be posted to Wikipedia for preservation and distribution.
