RSS feeds are used for syndicating news, articles, blogs, and virtually any other regularly changing content on a web site, including this one. You can simply open an RSS feed and use it to see if there is any new content on this site or you can set up a server-side script to parse the feed and add the links on your own site pointing back to the original article. If you use Firefox and want to create "Live Bookmarks" to the RSS Feeds, then do the following. First click on the link to the feed you want to subscribe to. Then copy the URL that pops up in the new window. In Firefox, open your bookmark manager. From that screen click on "File" and then "New Live Bookmark". In the box that pops up, name the bookmark and then paste the URL that you had copied. Viola! You should have a live book mark that contains the feed to the category that you selected.
