You mean individual subforums for each nation? If so, I'm afraid that won't happen. As a general rule, we are trying to make the forum layout simpler, not more convoluted, and adding subforums and subsubforums doesn't accomplish that. I'd suggest using the Draft option if you want to do WIPs. In the case of actual factbooks, it'd be better for you to make your own national thread, rather than get a whole subforum.
