Meepcraft should just add some additional books for every side server in MeepCraft. For example there can be a sign at towny alpha that gives you a book describing towny commands and how to get a town. It can throw all the towny information that is needed first and then all the advanced commands at the end.
Books like this would be good for all servers of Meepcraft.
Meepcraft could have a book describing how to play halo and tips, the same type of book for Skyblock and KitPvP and every game Meepcraft has.
If this isn't worth some staff's effort you can easily have a staff ask someone in chat to make a tutorial book for gamemodes. If you don't want to ask you can hold a competition
