>Can I use RSS to place headlines, like UT's, in my website by RSS means?

Yes. RSS (Real Simple Syndication) is XML. There are different standards, like RSS 1.0, RSS 2.0, and ATOM.
Just pick one an you'll be fine.

You have to set your server to run a process every hour or whatever to read and parse the RSS feeds. There are already some commercial and shareware programs to do that, but you could do it with VFP or any other. Search Google and you'll find them.

For publishing you could use a tool like ListGarden.

>Pardom me if this is a quite naive question, I just had my first contact with RSS a few days ago, and couldn't understand it yet (although I got to many websites dealing with it...)

Just now a first contact? You mean you have not subscribed to my RSS feed (or any of the other fine VFP Bloggers yet)? Come on Fernando! You are missing a lot of good info! (see UT Bloggers page or http://fox.wikis.com/wc.dll?Wiki~BlogWatch for a good list).
