Hum .. if we're going to make an event.. I think the roleplay academy is a good idea.
There could be weekly courses for newbies including everything you can do in the game.
They would learn how to roleplay in any situation. You are patrolling and you get engaged, you are trading and you get pirated, you're smuggling and you are arrested by a police force, an enemy country ship enters your territory and your have to take care of this issue. Each sessions could cover an average of everything that happens in the game. Maybe even some guy acting as if he was a newbie breaking the rules and then the event holder, as an example, shows them how to deal with it (I.E. explain him what he is doing is not right. And if he doesn't listen warn him that he will be reported and that a screenshot of his actions have been taken)
