           this.page.identifier = '<?PHP echo $title; ?>'; 
           this.page.url = 'http://tech-in.org/submitted_ideas/idea.PHP?id=<?PHP echo $idea_id; ?>'; 
         } 
       }); 
    } 
    var disqus_shortname = 'techinorg'; // required: replace example with your forum shortname
    var disqus_identifier = '<?PHP echo $title; ?>';
    var disqus_url = 'http://tech-in.org/submitted_ideas/idea.PHP?id=<?PHP echo $idea_id; ?>';
    var disqus_title = document.getElementById('disqus_post_title').innerHTML;
    var disqus_message = document.getElementById('disqus_post_message').innerHTML;
 
 
    /* * * DON'T EDIT BELOW THIS LINE * * */
    (function() {
        var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
        dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js';
        (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
    })();
</script>
