Adding "sold" to my sale thread on Market place

[pianoman]

How do I add "sold" to the title of my marketplace thread? I don't see any drop down pre-fix window or the option to edit my starter post in the thread. Although is says "you may edit your posts" I don't see any option to do so . I must have missed something because many have managed it before me.

Just reply “sold” in the thread and I will edit and close the thread

Thanks ! The FAQ does say that I'm sure but for some reason it wouldn't go into my head !
