I am only interested in a few of the sub-forums here, thus i filter my search for "new posts"
so it will only show what is relevant to me. This is how you do it:

This specific example gives you all new posts EXCEPT from the forums listed.
You can also use "include" in the exact opposite manner....!
The above will give you only posts from these forums.
If you go to the front page where every forum is listed (http://diablo.incgamers.com/forums/forum.php)
If you hover over the forum name, you'll see the URL in the bottom of your browser.
For example, Diablo Story and Lore has:
The bold-marked number is the id which you want to add to (or remove from) the list.
