An RSS feed is how a website is able to broadcast a content update. Once a posting/article has been added the RSS feed picks it up and pushes it out to the people who subscribe to it. If you type in the URL of the feed you can see all of the stuff that gets posted.
Thanks for the info!
Ok - that makes sense.
Don’t know if I’ll do it, but it’s nice to know it’s there if I want it.
