Bulletin Board TabYou use the Bulletin Board tab in the Bulletin Board (SP) application to create and post messages on the Bulletin Board.
When you compose a message, you define a posting and an expiration date for each message. The posting date indicates the date and time when the message should be displayed on the Bulletin Board. The expiration date indicates the date and time for the message to be automatically removed from the Bulletin Board.
You can also designate a specific audience for viewing your messages.
