I want to change the title of a thread in Buy, Sell, Trade, but it doesn't seem there are any options for me to do that. I can't neither delete the thread and start a new one with the new title. How can I go about this?
You have likely run out of time: "If you would like to edit (or delete) your posts, you can do so within 8 hours of making the post. After that, it is not possible for you to edit or delete the posts you have made here." https://www.digitalpoint.com/help/policies
If you edit/bump the thread, you can edit the title under "Thread Tools" for 6 hours after you start the edit window.
