Mail & Comments moderation ???
There is no moderation of comments or Mail messages is there? approve or reject. Mail messages can't be marked as spam or user can't block a user and don't get confused: Admin can block any user but a user that is registered on a site can block another user from posting comments or from sending spam mail.
I have add these request in separate for voting.
