Why associate any account you use with an email address you don't check.

Point taken. Yes that could be a possibility, but with something in the system, it takes up 0 time from any admins/mods so the "mailman" is incorrect. Also so what if you get the messages and you don't check it? Who does it harm? Right now if someone has a non-active account and email, then nothing happens. This would still be the same, But if they had an active email but not account they would be like, [quote]Oh thats my friend waiting for my relpy!" So they would BECOME more active.
I know you will probably say, well what if people don't want the emails, then give them a "no notification" setting!
