absolutely! one button for an RHP message, and one for an email too? or just the RHP? With the existance of RHP messages, I'd be prone to avoiding email myself.
could we have an ignore list for RHP messages (and don't send email to?) too? Not that I've any need for one, but it seems a wise precausion should someone start getting silly (e.g. there was some chat of a nasty hounding incident on another forum).
