title: Amazon Mechanical Turk 'custom' submit via web interface
body: <p>Is there any way to trigger the submit form on Mechanical Turk via a button which isn't their provided 'submit' button? (I require it to submit an empty form to speed up workers time)</p>
  
  <p>I've tried this:
  <code>$('#mturk_form').submit();</code> but a "There was a problem submitting this HIT" warning/error returns.</p>
