This is what I found on a cursory look through, some of the other posts seem worthy to keep even when the character is gone. (Such as the Japanese law list by Naruse.) Some of the others seem like they could be consolidated into a new post, and some others should probably be looked at and re posted (such as the school stuff). There's probably more but these seemed to be the obvious ones.
