"The User Directory Web Part provides an easy to use, SharePoint-based, self-service directory that allows users to maintain user information in the SharePoint user profile database or Active Directory. View your user organization in a user-friendly tree view by organizational chart or alphabetical order by last name. Users can view all profiles but can only edit their own depending on permissions set up for the type of directory service selected. With the ability to view, search and print user profile information (such as resume or skill set), your directory services now provide value to your users as well as your entire company."
