Let's say you're making an adventure map where the player must enter the right password to get into a castle. Is it possible to make the guardsmen testificates buy off a book from the player containing the right password in it in exchange for a lever? If you published it under the same username, I'm pretty sure it could work. But would you be able to do that with any player?
I'm not making an adventure map soon, but maybe this information will be useful to others who are.
