There is something confusing about the two. Knowledgebase issues are grouped into categories, but can be tagged with help topics (and parent help topics). When someone searches the knowledgebase, they are presented with a pulldown to "Browse by Topic," and these are the Help Topics, not the categories. But that "Browse by Topic" feature doesn't even appear to work--selecting a topic doesn't seem to do anything, and I have all of my FAQs tagged to help topics. So why are help topics associated with FAQs?
