For instance, the history category has a list of forums ordered by chronology, aka early Slavs -> Kievan Rus -> Mongol period -> Rise of Muscovy -> etc, etc.
I was wondering if people might perhaps be frustrated to see so many forums on the front page. It is possible to make them all into subforums under a General History-type forum, but the problem then is that people would have to move one level deeper if they want to talk about a specific period.
So what are you opinions? Do you use sub-forums or not?
