title: Close popup after form is submitted
body: <p>That seems to be a common question with multiple replies but I couldn't get any of them work.</p>
  
  <p>I'm working on WP. Currently I'm using a plugin that shows a pop-up as soon as a not logged in user lands to the website. In the popup I use an optin form (created through MailChimp).
  When the user submits his info, a new tab opens moving him to the email verification page.</p>
  
  <p>The problem is that the popup remains open in the first tab.</p>
  
  <p>I would like it to close as soon as the data are submitted. Is that possible?</p>
  
  <p>Here's a <a href="http://deals.karditsa.topgreekgyms.gr" rel="nofollow">link</a> to the website.</p>
  
  <p>Here's the code of my form:</p>
  
  <pre><code>&lt;div id="mc_embed_signup"&gt;  
  &lt;form action="http://fitnessforum.us6.list-manage.com/subscribe/post?u=d6acf8949532b107b7b21c9d0&amp;amp;id=1304ea7322" method="post" id="mc-embedded-subscribe-form" name="mc-embedded-subscribe-form" class="validate" target="_blank" novalidate=""&gt;
  
  &lt;div class="mc-field-group"&gt;
  &lt;input id="firstname3" style="width:260px;margin:5px 0;background-position:95% center" type="text" value="" name="FNAME" placeholder="'Ονομα"&gt;
  &lt;/div&gt;
  
  &lt;div class="mc-field-group"&gt;
  &lt;input id="primaryemail3" style="width:260px;margin:5px 0;background-position:97% center" type="email" value="" name="EMAIL" placeholder="Email"&gt;
  &lt;/div&gt;
  
  &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; 
  
  &lt;div class="clearfix"&gt;                  
  &lt;input name="subscribe" style="width:305px;margin:4px 5px 0 0" class="simplemodal-close button_link hover_fade large_button silver button_widget" type="submit" value="ΣΤΕΙΛΤΕ ΤΟ ΔΩΡΟ ΜΟΥ!"&gt;&lt;/div&gt;
  &lt;/form&gt;
  &lt;/div&gt;
  
  &lt;div style="text-align: center"&gt;
  &lt;p class="under_button2"&gt; Το email σου είναι ασφαλές στα χέρια μας.&lt;/p&gt;
  
  &lt;div class="af-clear"&gt;
  &lt;/div&gt;
  
  &lt;/div&gt;
  &lt;/div&gt;                  
  &lt;!--End mc_embed_signup--&gt;  
  </code></pre>
