Sorry, if I add an e-mail address to my profile 'about:' field it can be seen by everyone. Also even if I have my e-mail address in the "email:" and "notifo:" fields I don't receive any notification.
You can subscribe to HN Notify to get email notifications of replies. No, I don't have the link. No, I cannot look for it right this minute as I have an appointment.
It would be even cooler if I could tell it to ignore replies to relatively recent comments (say, less than 24 hours old). I don't want to get flooded with notifications about threads that I still have open in a tab somewhere.
