I was wondering about this myself. But since there are so many different forums, links etc. you would have to set your link depth to a level where you would quickly max out your channel/size allotment.
What I did was just add the main page to my custom channel so I could get a quick overview of new news and what was being discussed in the various forums on my train ride to class.
