So what is RSS? RSS stands for "Really Simple Syndication." Think of it this way: It's like having your own personal news service. RSS allows you to collect "feeds" from websites you want updates from. When a site updates, you'll know about it by checking your feeds!
How can I use RSS, if it's "really simple"? If you know how to use bookmarks (or favorites) in your web browser, you can figure out how to use RSS. To get the Buffettman's feed, go to this page. It will look something like a newsletter listing with dates and titles. Next, use the bookmark feature in your web browser to have it remember this site. When there's an update, your browser will display a number or alert telling you about it.
You can also use the RSS feed for the Buffettman's calendar page. It looks the same, you bookmark it the same, but you'll get information about upcoming shows.
But I don't know how to bookmark stuff... Now what? Here are some links that may help you learn about bookmarking: Internet Explorer Mozilla Firefox Safari
