title: Default name in Drupal user login form?
body: <p>Is is possible to pre-enter the username via URL in the Drupal user page, e.g.:</p>
  
  <pre><code>www.example.com/user?name=peter
  </code></pre>
  
  <p>such that "peter" is filled automatically in the <code>Name</code> filed and so the user is required to enter the password only.</p>
