XF 1.3 Make threads in sub-forums also show in main forum

When I place a thread into a sub-forum, it doesn't show up when you click on the main category, you have to click on the sub-forum in order to see the threads/posts.

Is there a way to make it so that when members add threads to the sub-forums it also show's up in the main category.

here's a link to show what I'm talking about: http://www.intominecraft.com/forums/minecraft-news.2/

There's a thread in the Featured Top Plugins forum, but you can't see it when you click that link, I'd like for it to show if possible.
