title: Addthis: Changing Description, Title, and Url being sent
body: <p>I am building a forum in PHP and I want users to be able to share the title and description of each post to facebook, twitter, ...etc using the Addthis social plugin. Here is the code Addthis has given me:</p>
  
  <pre><code>    &lt;!-- AddThis Button BEGIN --&gt;
      &lt;div class="addthis_toolbox addthis_default_style "
          addthis:url="www.example.com"
          addthis:title="Example Title"
          addthis:description="Example Description"&gt;
      &lt;a class="addthis_button_preferred_1"&gt;&lt;/a&gt;
      &lt;a class="addthis_button_preferred_2"&gt;&lt;/a&gt;
      &lt;a class="addthis_button_preferred_3"&gt;&lt;/a&gt;
      &lt;a class="addthis_button_preferred_4"&gt;&lt;/a&gt;
      &lt;a class="addthis_button_compact"&gt;&lt;/a&gt;
      &lt;a class="addthis_counter addthis_bubble_style"&gt;&lt;/a&gt;
      &lt;/div&gt;
      &lt;script type="text/javascript" src="http://s6.addthis.com/js/154/addthis_widget.js#pubid=rd-39e8r89e9er8er989"&gt;&lt;/script&gt;
      &lt;!-- AddThis Button END --&gt;
  </code></pre>
  
  <p>I was able to change the url to another I have specified, but changing the title and description has no effect.  In fact, they do not even show up when I click the share button and post it to my facebook wall.  What is the proper way to get this to work?</p>
