RSS stands for ‘Really Simple Syndication’ or ‘Rich Site Summary’. So, what does it do? Most people search the web and when they find a useful site which they would like to come back to, they either note the URL (Uniform Resource Locator - the ‘web address’) somewhere, or better still, save it to their ‘Favorites’ as a bookmark to come back to. Whenever you want to check if there’s anything new on that website, you would have to go back to it to check.
Well, with RSS, you don’t have to keep going back to the website to see if there’s anything new, the new stuff comes to you! Once you set up a RSS ’feed’ using a RSS reader, you don’t have to keep checking that website for new stuff, you just have to log in to your RSS reader and any new stuff will be posted there. Once you’ve read the new info, you can mark it as read, and hence keep easily up to date with all the new information whenever it’s posted to the site. As you can see, lots of time is saved by not having to keep going back to a website to check if there’s anything new, and there are many more benefits. You can set up lots of ‘feeds’ from different websites which all appear in one place in your RSS reader, and hence keep up to date with many subjects, news, etc.
To set all this up you need to find a website with a RSS feed - most news sites, forums, and blogs now have these. You can recognise a page with a feed by various RSS icons, the most common is this one:

but some just have the letters ‘RSS’, usually somewhere near the bottom of the page. You also need a RSS reader - there are many free ones on the web, lots where you don’t have to download any software, but you just have to register. This bit has now just got much easier with the new Internet Explorer version 7 - this has a RSS reader built in. The icon, as above, glows orange when it detects a feed on the page you’re viewing, so you just have to click on it and subscribe to the feed. Blogs are common places to find feeds, so how would you create a feed from this blog, so you wouldn’t have to keep returning to check if I’ve written anything new? Just click on the RSS icon on the toolbar of Internet Explorer 7 (it’s next to the home icon on the top right), which should be orange when you’re viewing this page, and subscribe to the feed by clicking the relevant link on the resulting page. When you want to view all the feeds you’ve subscribed to, just click the ‘favorites center’ star on the Internet Explorer 7 toolbar at the extreme left and click the Feeds tab.
