how can you add "other parts"? Even if you code a script that reads a directory for .html files, this wont do the trick because not every html files should be included into the list as some might be private, some might be SSI includes etc.
All you can do is to be happy with forum list (I'm NOT talking about forum COUNT, I'm talking about the entire list, a forum map) or have a portal/content management script to have your pages in your MYSQL so that you can query your db and get a list.
