Believe it or not, pointing our the duplicate thread IS helpful. It directs people to the one that has a couple of replies (inculding one from me) and it keeps all the replies on one thread for your benefit.
You cannot delete your own thread. All you can do is try to get a moderator to do it for you. Go to the "Options" menu, click on "Report Inappropriate Content," and ask the moderators to remove this thread.
