Please Please Please Delete Posts that are sold!

What I like to suggest is that a seller is responsible for their own post, and once something is sold, reply with sold. Then anyone reading the page can see "sold" and will know that it's sold. It's easy, it's free and doesn't require any work from anyone other than the guy that just sold something.
I don't have a lot of software options, it on or off. No option to mark something closed after it's got some sort of text entered, it's just a thread. It can't manage itself, and I'm not managing it for the seller. Just mark item sold. Then a buyer can look at the end of the thread, and if it says sold, look at other threads. If it says nothing, and isn't from 2002, send a PM. If the seller replies with sorry, it's sold, it's sold. If they don't reply, it's probably sold or they died.
I don't understand why we keep suggesting ways to make this more difficult than typing four letters. It's so easy, anyone can do it.
