I can watch the JBoss Mail Server Forum from my Firefox feeds. Its the same way you can read your favorite blog. I wish I could say it was increadibly straightforward, but the forums don't yet put that little HTML tag at the top that advertises this feature:

     <link rel="alternate" type="application/rss+xml" title="RSS 2.0"
                      href="http://www.jboss.org/modules/bb/rss?f=186"/>

However you can just create a new live bookmark by clicking the little orange icon at the lower right-corner of the browser. Then right click on the new Live Bookmark, click properties. Then replace the feed URL with: http://www.jboss.org/modules/bb/rss?f=186 for the JBoss Mail Server forum. Since this is the most important forum, do that right now.

If you want to watch other forums you can do the same thing by just capturing the forum's id (it is displayed at the end when you go the the main page of that forum).

The feeds are listed in the same order as they are in the forum, meaning things that are stuck to the top...stay at the top here too. Its a convienient way to watch ongoing topics. It would be nice if you could get comment feeds too, but that is not yet supported.
