That's right, each time there is something new posted to the sites you have signed up to, the articles and bits of news will automatically be sent to you. You can read at your leisure, sort them into files or delete, as you see fit.
For ease of understanding and showing how the RSS Feed works, I have found this video. The video is quite old and it should be noted that Google Reader they reference, is no more. Other than that, it spells out signing up for RSS Feeds in easy to understand and follow instructions.
There is one installed on this page, too. Down at the bottom. On the right hand side. Below the Archives and Categories. If you enjoy reading our Morning Muse, be sure to sign up for our RSS Feed.
