Alright, so is that the "Weird sibling misunderstandings" Arc over? Yes? Good :P

Speaking of the birthdays and such, I'd rather go with a pretty loose interpretation of the things. In my opinion, it's going to make things real weird if we write down the birthdays and it so happens that some char's birthday is six months from when we start in ingame time, because that's probably going to take an absurdly long amount of time to reach. Might as well leave it open so people can throw their birthdays around, within reason. Plus, the birthday things forces us to keep real close tabs on exactly what day it is, which may or may not end up backfiring.

As for items... that sounds interesting enough, at least writing down what our chars prefer to use/are trained in using as weapons. If need arises there's always the possibility to grab a chair and smash it on some monster's head, anyways; and I doubt anyone's clumsy enough to not know which end of a sword to stick into the enemy even if they aren't formally trained (that has always bothered me in games, tbh).
