This could probably be rearranged quite a bit, but not sure if it'd make a difference. It could I guess be mailed to people in a conversation link when they make an account, or somesuch once it's fancy.
I dont think it should be against the rules for asking why if you vote down on saves, i think it shows how to fix it because if it is voted down for a reason then saying why helps me fix it therefore improving the save overall.
