You can set up for RSS feeds directly in your AdminCP Its called "RSS Feeds" and its right near the bottom
You can then set up a forum as you say and have your RSS feeds added to that, It really is that simple, even i've managed to do it

You just need to create a new user and use that user as the poster.
and thats it, Once set up in your Admin CP, just sit back and wait for the news to appear at the intervals you specify.
Good Luck
