I would like to have an option to protect download with password, but I want this password dynamic, The user who upload can choose to put or not to put the password. Then in a topic he post the link. People who reply in the topic will get populated in a table and then Poster can choose to send the password to those who replied. And pass are sent automatically via PM .
I am willing such system to avoid lechers and people who don’t appreciate work of otheres and just download things without giving thanks or comment to the autor

Is this possible ?
