Q. How do I add an RSS feed into announcements?

An RSS feed can be added into Announcements in your course, but it will result in many notification e-mails. Every time a new item is added to the feed, it will create a new announcement which will be e-mailed to the students. The result would be students receiving an overwhelming number of e-mail notifications.  If you would like to use an RSS feed in your course, a better option would be to add the RSS feed to a wiki page and link that wiki page to the Canvas course.
