I think it is not so good that the check box for Manager Notified activates Hide for 30 Days. The way I first notify managers (unless I have already a working relationship with them) is usually to write a public comment on the erring profile saying: "Have you noticed the error report?" and then a link to the error report for that particular profile, so they can see for themselves (and perhaps also notice other errors). But if there's a Temp Hide, they will not see the error I'm trying to alert them to.
