This is just a simple suggestion for the forum. When you go to the main page of the forum, there are main header catagories, and then smaller sub catagories under those that you can click. If you go into a sub catagory, then you have the option of clicking the header catagory as a link and see all of the posts for the various sub catagories together.
Could the website person make it so that from the forum page directly you could click directly into a header catagory and see all the posts within the sub catagories?
Website person making a test.... more testing
