I thought about that option.
well... in the game, the birthday is seperate from the rest... it's *your* birthday, not the chars 
if there is some better concept, we can work on it.
well for rpers they probably came up with the characters birthday. like when and if you do it once you sign it something special comes up "an anbu of the village comes up and says yes the leader of the village lost all the files we managed to get most of them back but we didnt get the birth days back may you tell us yours" then you put in your characters birthday and on the side it will have an option (show on profile or no) and you cant run form him either you ahve to do it.
