I use the following Javascript snippet to autoembed images, videos and links in my forums. I wish to use this for the same purpose on my index page which uses VBA 4.1.2. The code only works in the .postbody class in the threadbit

Code:
selector: '.postbody',
no matter how I try to edit this part I always break it as I know next to nothing about coding. Also I don't know what class to use, firebug does not make it obvious. I was thinking it would be postcontent but I have no idea how to add a second selector... Looking for a little assistance.

Any help would be appreciated

<script type="text/javascript">
    var _path = 'http://scripts.embed.ly/anywhere/';
    var _embedly={
      key: 'xxxxxxxxxxxxxxxxxxxx', // Change XXXXXXXXXX to be your Embedly Key, http://embed.ly/pricing
      method: 'replace',
      endpoint: 'preview',
      theme: 'dark',
      selector: '.postbody',

      g.src=_path+'anywhere.js';s.parentNode.insertBefore(g,s); }(document,'script'));
