Currently, any RSS feed will only pull from all news forums. We do have plans on changing this in the future, but what this means currently, is if you subscribe to GZDoom, for example, you will get all of DRD Team's news. This feature uses phpBB's default RSS feed system, which used to only be available as a mod.
The subscription link is http://forum.drdteam.org/feed.php?mode=news - if you're familiar with feed.php you may change the parameters as you see fit for your favorite reader application.
