I've been searching for this as well, or a good CSS script I can apply to the specific nodes to achieve this.
I have main categories for different regions and sub categories of topics within those regions. Then I remove the node display off those main categories and create links to each region sub category so they each have their own mini forum. Creates a cleaner looking forum that doesn't seem to scroll endlessly.
Problem is, those sub categories don't look like categories which creates a messy looking page.
