title: How to disable Personal Contact Form display in User Registration
body: <p>I am new to Drupal 8. 
  I am setting up a simple site and do not want to allow users to contact each other. However, I do want to use forms such as Register for an event. </p>
  
  <p>I have updated the user registration form by adding additional fields, such as first name, address, phone, etc. </p>
  
  <p>/user/register displays the <strong>Contact Settings</strong> box:</p>
  
  <p>"Allow other users to contact you via a personal contact form which keeps your email address hidden. Note that some privileged users such as site administrators are still able to contact you even if you choose to disable this feature."</p>
  
  <p>with <strong>Personal contact form</strong> check box unchecked.  </p>
  
  <p>How can hide the display of the Contact settings box completely?</p>
