What is the Announcements tool?
The Announcements tool allows for the delivery of messages to an entire site, to groups, or to specific rosters within a course site. Participants will see messages that have been made available to them in the Announcements tools of the site displayed in the Recent Announcements area of their Home site, as well as within the site itself. These messages can be set to show immediately, or to show during specific dates. Email notifications can be sent to alert participants of an announcement.
Note: For instructions on how to add this or any other tool to your site, see How do I add a tool to my site?
