Mahna Mahna (Do doo be-do-do)

If you delete content, it is gone forever, so be sure before deleting.  If you are unsure, unpublishing the node is an option.  Unpublished nodes are not visible to anonymous users and do not appear in views (assuming the view has been properly configured).  If you unpublish a node, make sure to remove it from all menus.

To delete a node, click on the edit tab.  Scroll to the bottom of the page, and click the delete button.  Make sure to remove all links to the former node from your content.
