Some tools (e.g., Announcements, Resources, and Syllabus) allow you to send email notifications to site participants (at their email addresses) when you add new items. You can specify a low-priority email notification, which will be subject to each participant's notification preferences, or high priority, which will override individually set preferences so that all site participants receive the notification.
Other tools (e.g., Blog and Podcast) let you subscribe to a RSS feed by using a Podcatcher for instructor’s podcasts or Feedburner for course blogs. By simply copying and pasting the url into your iTunes you can have your podcasts automatically downloaded. Announcements can even be modified so that students can receive an RSS feed of course announcements.
