It is possible to subscribe to a Campus Pack blog, wiki, journal, or podcast and receive an email when a post or comment is added or edited. The emails are sent out every hour (or so) and any changes that have happened since the last email will be summarized and sent out.
Each user must subscribe to the blog or wiki. Unlike a forum in Moodle, the instructor cannot set subscription preferences for the whole class.
To subscribe, enter the blog or wiki and under the "Settings" menu to the mid-right of the screen, click on the "Subscribe" link. Check the box to confirm your subscription. You can unsubscribe at any time by unchecking the box.
