Forum navigation

Sorry to display such ignorance, but I'm trying to navigate the forum postings. I visit Home>Forums and there are 6 topics listed, such as "Getting Started" and "Community" etc, and so I click on one of these topics to try to view the posts in that topic, but it says "no topics found here". At the same time, I can search for a key word and the results are plentiful and many of the threads are members of those topics. Why is searching apparently the only way to view the threads in the forum? If not, please enlighten me.
