How to change title of a Thread

Hey guys,

I'm new here. I have a Surgeon Remedy, 338 Lapua listed in the classifieds. Been the better part of a week with hundreds of views and no bites... Therefore I have reduced the price by $500.00.

My question is, can any of you tell me how to change the title of the thread? I want it to show that the price has been reduced so those who may have been interested can see that without having to find the thread and read down to where the price is stated.

I'm confused because after the thread had been posted I saw a typo I wanted to fix and stumbled onto a place where I could change the title to reflect that it had been updated. Now I can't figure out how to do it again.

Related question: I have asked a couple people via PM, but haven't been able to figure out how to change the status of a classifieds listing to SOLD/EXPIRED. It seems that some people have options that I don't have based on their suggestions. Do any admins know why this might be happening? @Len Backus Thanks!
