Title changing?

Hey guys, I don't know whether this is the place to post this or not, but I did search around for about 10 minutes before deciding to make this post for the right place to do it, and my eyes are rather lacking in skill...

But if this would be the place to do this I am wondering if I can get the title of my thread changed:http://www.sythe.org/showthread.php?t=410293
From: "UK US SMS PINS"
To: $5 AUD PINS

I also tried editing the thread because I remember once when editing it had an option for titles, but I couldn't find that option.

And once again, if this isn't the spot, sorry! >.<
