Adding threads option to comment poster

In the attachment you will find a script which works, comment poster for a forum of the portal index dot hr This forum has limit for new users of sending only 2 messages per hour. I found an expoit of this, if you post manually and you open 30 tabs at once and fastly submit 30 messeges you will succeed and pass this limitation. This is what i need threaded posting. I've provided you this script so you can copy paste some of it's code if you like, it's fully functional. So what i need is a threaded comment poster which is able to post at least 30 messages or more at once using threads. Since i've already provided the source of the comment poster for this website and you can modify it to work as threads im offering 50$ for this job.
