The only thing I can think of is there is a way to minimize, or maximize, each section of the forum.
For example, at the top we have the "Community" section. In that section we have the Virtual Campfire, Politics, Gun Rights, etc.
Now, if you look at the top of that section, where it says "Community" on the left side, over on the right side there is a small "button" that has either a plus sign or a minus sign.
That is how you minimize or maximize that section. If it's a plus sign there, you have it minimized and you won't see any of the forums in that section.
