Drupal provides a number of ways to find out who has been visiting the site and who has been posting content:

• User list page. A table of users with their last access to the site.
• Drupal logs provide userful statistics and system-generated messages:
  • Recent hits. Logs of access to individual site pages. Provides information such as username, IP address, and referring page.
  • Referrer logs. Site referers for both internal and external links.
  • User logs page. The most recent session information for users.
  • Special logs. Information on recently added and updated nodes and comments.
• Recent posts page (link available in the main navigation menu). The most recently updated nodes, including those with new comments. Logged in users will find a red asterick * beside all new or updated content.
• Content configuration and comment configuration sections. Each provide tables listing nodes and comments respectively from which an administrator can edit, view, or delete.
