If you are using a feed reader, click on the links marked with the RSS feed symbol at the top of any page.
Internet browsers like Internet Explorer (IE) and Firefox make subscribing much easier by showing the RSS feed symbol either on a toolbar or in the address bar , indicating an available feed. Clicking on that symbol will subscribe you to the feed using your selected news reader.
If you are using other software that can read RSS feeds, click on the link to the feed to which you wish to subscribe, copy the URL address of that feed from the web browser window, and paste it into your news reader.
