As a system administrator, you can delete all the articles in a particular Bulletin Board. Be sure you have a data backup before deleting, as this action cannot be undone.

1. From the Portal Page, choose Bulletin Board > Setting.

   If you are not already logged in as Admin, enter your admin password when prompted.

   Select Delete All Articles.

2. From the Bulletin Board drop-down menu, select the bulletin board containing the articles to delete.

3. Select a time period to delete articles.

4. When done, click Delete.
