How do i change a title to my thread?

This thread http://www.sythe.org/wow-membership/1847228-selling-two-wod-cd-keys.html if any mods wants to change it for me.

Anyway i would like it changed to "Selling WOD CD key for RSGP, US region, amazing price!" because i no longer have 2 cd keys, and am selling the last one for a much cheaper price. Also, the last person i tried selling it to was in the EU region, so obviously it didnt work, and now he has my key. I dont think he will do anything malicious with it, but anyway id like to avoid future conflicts like that.

So basically i want to change my title to better reflect what im selling, how do i do that? I tried changing it with advanced but it didnt really work.

 

You can report the thread using the '!' on the top right of every post.
Just say your new title in the report field, and a staff member will take care of it for you.

I've changed it for you now, next time you know what to do
