By default, students may only read announcements that have been posted by instructors and other instructor-type roles. Instructors may set the announcement display options for users within a course site.
Select the Announcements tool from the Tool Menu of your site.
You may select to display site announcements in one of the following ways:
By default, each site is automatically given an RSS URL that can be used to subscribe to public announcements. If you would like to customize this URL to one that is easier to remember, you may type the desired alias into the RSS Alias text entry field.
After you Update to save that change, your alias will replace the auto-generated portion at the end of the URL.
If you would like to specify the default number of days in the past or number of announcements to be display, enter those values in the fields provided.
