How to unsubscribe or email notice?

How to unsubscribe all email notice?

What I mean is I don't want email notice of any kind. How can I do that? Thanks

I'm not sure if that can be done. Maybe one of the admininstrators will know.

Go to User CP, click Edit options and there should be a small rolldialog in the section of subscribtions. Set the roll to "do not subscribe".

Got it, thanks very much.
