In the Bulletin Board application, you can create messages about critical problems and incidents that you can broadcast throughout the organization. You can also view communication logs from service desk agents and their users, and communications that are generated by workflow processes and escalations.
You can specify an audience for a message. If you do, only members of that audience can see the message. You also specify the date and time for the message to appear and to expire.
Recipients can view bulletin board messages from the navigation bar of an application or from the Start Center.
