title: “Clear Form” event from Facebook’s registration plugin?
body: <p>I’m using Facebook’s Registration plugin <code>&lt;fb:registration&gt;</code> for new users to my site and, if they are logged in to Facebook, I display the plugin registration form. If the user selects the “close” button on the email portion of the form and then selects ”Log Out”, I get the logout event and remove the Facebook form and restore our own. If, however, the user selects the “Clear Form” button, it simply clears the Facebook form.</p>
  
  <p>If the user isn’t going to connect her Facebook account, I’d prefer to display our  form when she presses ”Clear Form”.</p>
  
  <p>Is there an event from the Facebook plugin that will tell me when the user selects “Clear Form”, or is there some other way I can achieve displaying the Facebook form only if the user is connecting her Facebook account?</p>
  
  <p>There is an <code>fb_register</code> attribute that provides this basic functionality by removing the “Clear Form” button, but it also displays a message that says “you must use your Facebook account” to register, which is not true in our case.</p>
