Showing Post Counts of Sub-categories

[DarkReaper]

When a category has sub-categories that aren't shown, only the name of the category is shown, nothing else - no posts, replies, or even a post indicator. How can I make it so that for these categories, all the replies and posts from its subcategories are added up and shown, as well as the last post time, and a post indicator being shown?

Just found this, but in a better form. Not only can the above be done but the sub-forums can be shown under the parent forum
