Are you tired of people PMing you asking if you still have items that are in your trade list?
Tired of people asking what BINs are?

If you could edit the very first post of your trade threads at all time, the first post would always be updated. Some people are too lazy to look for other posts stating BINs or if the item(s) is sold. Some people don't always look at the last post, only the first. They offer on an item that has a current offer of more than their offer, or is already sold.

If you could edit it at any time, you wouldn't have to worry about people offering on items you no longer have.

Please post yes/no.
Thanks.

You cannot for safety reasons. It reduces scamming/bmness.
Just update it each bump.

How can you scam someone by updating your post?
Some people don't look past the first page.

You can change prices and other stuff like that.
It's not going to happen.
