Use an announcements list to post news, status, and other short bits of information you want to share with team members.
By default, creating a SharePoint site creates an announcements list called Announcements, a view of which appears on the home page of your site. You can create and access additional views of this list from the Documents and Lists page. Announcements other than the five most recent disappear from the home page but are still available on the All Items view of the Announcements list.
Note The features on your site may vary, based on the template your site uses.
You can set an expiration date for an announcement. When the expiration date is reached, the announcement disappears from the home page automatically. However, it is still available on the Announcements page.
