Members can close their thread once the item has sold.
Did you know that you can close your own thread in the Forsale forums once the item has been sold, traded or if you simply change your mind? As long as you are the thread starter, you have an option in the additional options box (below the text box) that allows you to close your thread. Once you reply that the item is sold to member "X", simply scroll down and check the box "Close this thread after you submit your message" (please see screenshot below). The thread will now become locked.
This helps to let other members know that the item is no longer available. It also helps to keep the thread from bumping back to the top while leaving it intact for others to search the threads to find information such as the going rate for product X.
More new and exciting features will be released soon to enhance your experience!
