title: Change MailChimp's success/error message
body: <p>I can't find this anywhere. Can anyone who's familiar with MailChimp advise?</p>
  
  <p>I've embed my form/input and there's some empty div's (below) which have error/success messages injected.</p>
  
  <pre><code>&lt;div id="mce-responses" class="clear"&gt;
      &lt;div class="response" id="mce-error-response" style="display:none"&gt;&lt;/div&gt;
      &lt;div class="response" id="mce-success-response" style="display:none"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>When I add custom text to the empty div's it just gets overwritten when the form is submitted so it's obviously getting the content from MailChimp somehow/where!</p>
  
  <p>Any ideas?</p>
