RSS feeds (it stands for really simple syndication, but you don’t really need to know that!) allow you to subscribe to web content such as blogs and websites. It helps you keep track of new content on a website without having to visit the site to see if it’s been updated. Browsers Firefox and Internet Explorer 7 make it very easy to subscribe to and read RSS feeds. We recommend that you use Firefox if you’re not doing so already. You can download it here:
How to use RSS Feeds in Firefox
You can either click on the orange RSS icon 
in the window where you type web addresses and then add the feed to your bookmarks, or click on the icon to the right of the blog name and follow the instructions. Once you’ve done that you just need to look at your ‘live bookmark’ to see if the blog has been updated.
The process in Internet Explorer 7 is very similar. Click on the RSS icon on the toolbar which will allow you to add the feed to your favourites.
