Well if you want to pull news from the forum, SMF has a general rss feed, but I don't know if you can set it up to only read from certain categories. yours is
http://www.dimx-gfx.net/index.php?type=rss;action=.xml (firefox lets you know when there is a feed on the page with the rss icon next to the site address.
If you want to have a page on your site where you post news articles (not in the forums) and have them fed through rss, try a news script. I personally like cutenews.
After a short google search I found this
http://www.scribbledesigns.co.uk/2007/01/2...machines-forum/ explaining how to get the rss feed for a certain forum. So say your news forum for instance. But it does say that if there are replies to the initial topic, that topic might show up many times on your feed, so maybe make the news forum read only.
If I'm still not hitting the nail right I'm sorry. Best I can do with the limited info you're providing here.
