Making user profiles publicly accessible in Drupal 7 How can I make user profiles publicly available to anonymous users and search engine bots accessing my website?

Details: User profiles are not publicly accessible by default. Without being logged in to Drupal, if you try to access /user/123 for example, you get the You are not authorized to access this page error message. I want to display the user profile details instead.
Simply go to /admin/people/permissions, scroll to the bottom of the page and turn on all check boxes for the View user profiles permission.
