The RSS system allows you to receive general information or thematic pages, every time you update your content without having to connect to the website.
To subscribe to the RSS feed you want just click on the link of the channel if you have a compatible browser (Mozilla Firefox, Internet Explorer 7, Opera, Safari, etc..) Or icon of any of the free services available on the Internet (my Yahoo! and Netvibes) in which case you should register with the service.
If you already have an aggregator program, select the files or RSS feeds that are of interest for content syndication. To subscribe to a feed, generally, you must copy the URL of the RSS file and write it into your aggregator.
