I'm making my forums, and I have a lot of sub-topics. Just like Digitalpoint. But on Digitalpoint, next to each forum, the sub-topics are listed underneath the forum. Like Sub-Forums: AdSense, AdWords, Sitemaps, Google APIs, Product Search. When I make sub topics, it shows the sub-topics after you click on the forum, not underneath the forum on the home page. What should I do to activate this?
Depending on your forum script get them automatically added, otherwise with older versions/different scripts you need to add manually each link by editing the main category's description.
