The Tracker core module displays a site's most recently added or updated content. The Tracker module also provides user level tracking, which allows you to follow the contributions of specific authors.
The Recent content page in Drupal 7 (or Recent posts page in Drupal 6) at
http://example.com/tracker is available via a link in the default Navigation menu block when the Tracker module is enabled - and the View named 'Tracker' is enabled. Menu items can be administered on the Menus administration page at
http://example.com/admin/structure/menu (Administer > Structure > Menus) in Drupal 7, and
http://example.com/admin/build/menu (Administer > Site Building > Menus) in Drupal 6.
The Recent content page contains a reverse chronological list of new and recently updated content. The list displays the content type, the title, the author's username, how many comments that item has received, and when it was last updated. Updates include any changes to the text, either by the original author or someone else, as well as any new comments added to an item. A red "new" will display beside the name of each node the current user has not yet navigated to. The My recent content tab on this page limits the list to the currently logged-in user.
