The Dashboard module provides a Dashboard page in the administrative interface for organizing administrative tasks and navigation, and tracking information within your site. The Dashboard page contains blocks, which you can add to and arrange using the drag-and-drop interface that appears when you click on the Customize dashboard link. Within this interface, blocks that are not primarily used for site administration do not appear by default, but can be added via the Add other blocks link. For more information, see the online handbook entry for Dashboard module.
