If you can't edit an old post it is better to create a new one with some different content and different title or note somewhere that it is a repost. It prevents other users from thinking that you're trying to promote the same article again for more money.
I don't understand!! It wouldn't let me edit the other one so I had to make a new one. Am I doing this wrong?
Ah, I see. They introduced a time limit on edits, but I thought it was 4 weeks. Might be lower I guess.
