Actually in any thread or forum within these forums you will see an option labeled thread tools or forum tools. When you click there you will see an option to subscribe to that thread or forum. This way you can get messages just on the exact things or parts of the forums you want to track.

Note that the forums also supports this via RSS. Just lick the RSS icon in your browser and select the feed you want. You can then copy that address and integrate it into whatever RSS syndication sute your using.
