Saud is right. Unfortunately, there's no <!--System:News--> command or anything like that. But that IS an interesting idea.
I could see this as a good idea if you wanted to have an optional new banner that showed up on all pages. A lot of people bookmark the forums and thus never see the news. If you go to Yahoo or other sites you'll notice that they all have a news banner of sorts that changes every 5 seconds or so and shows the headline and a short excerpt of the new article which can link you to the actual artical with forward and backward navigation buttons. Maybe that is too much but might be a neat feature to have the 3 or 5 most recent news Subject Lines in a changing banner box.
