Can someone explain how to close a for sale add?

Post "sold" at the bottom of the thread.

Most simply reply with a Sold or edit the title to show SOLD

There's enough traffic down there that most just die a death by volume and disappear off page 1.

IMO - anything after page one may as well be the Dark Web.

Make a post stating that it's sold or no longer for sale.

Every now and then somebody digs up an advertisement from 2009 asking if they still have it.

Thanks for the replys. Apparently you can't edit after a period of time passes.

That's so we can keep track of the corona idiots.

Just make a new post marking it sold.

Yeah if you could edit post months later. People be in there deleting posts from March as we speak..
