Document workspace sites created using SharePoint 2007, take advantage of platform features by providing a document collaboration space. Documents can be reserved by individual users for updating purposes. Document changes are tracked and assigned different version numbers for auditing and rollback. Changes can be made in a Web browser by dragging Web Parts onto personal or public pages where customization may then take place. In addition, themes can be applied utilizing a browser. A user or site manager can add an alert to a list or list item so that they receive an e-mail notification when changes are made.
