The Announcement content type is used for controlling the publication and expiration dates of time-sensitive content. Through using Announcement the contributor can set the node up to display on a defined date and to expire on a defined date. Content is not deleted, just hidden.
The Announcement content type is controlled by the Announcement module and the content within this node type is displayed in one of two provided blocks: Announcements: Small List and Announcements: Summaries.
Creating an Announcement node is very similar to creating standard OSU Drupal content such as Page or Story. The only difference is the inclusion of a Publication date widget and an Expiration date widget.
