Working and good standalone plugin

Very good plugin, works as expected.

If you want the button to follow when scrolling on the right side of your website:

put this code before the </head> in your header.php or header file

<div id="suggestPost">
 <?php do_action('wpcallback_button'); ?>
</div>

and in your main css file

#suggestPost
      {
        height:170px;
        right:0;
        position:fixed;
        top:150px;
        width:168px;
        z-index: 20;
      }

      #suggestPost a
      {
        display:block;
        height:40px;
        width:170px;
      }

Have fun
