How about a pop-up that says "Do not be harsh on the new users, forcing people to read the rules is pointless and an annoyance... Let them do it themselves. Pokemaster has a heads up for the rules anyways. Thanks."
To be honest, these have been asked too much. If it is a new user, we will approve or reject it. There is a term for this, known as Learning through Experience.
