What are RSS Feeds?
RSS originally stood for "Really Simple Syndication". It is a family of web feed formats used to publish frequently updated works such as news headlines, blog entries, etc., in a standardized format. So, if you subscribe to an RSS feed, you will automatically receive updates to the corresponding section of the website as soon as the new content is published.

How do I subscribe to an RSS feed?
To subscribe to an RSS feed, click on a feed to the left, and then choose to add a 'subscription' to that feed to your browser or news reader. You will receive and view RSS updates for the chosen feed.
