Hei, shouldn't i be notified by email if someone starts a comment with @wyrfel ? I don't get any email notifications at all, even though correct email address is in profile (it was pulled form my OpenID). Could this be a privacy setting in my OpenID? Or did i do something else wrong?
You only get (semi-)daily mails for new answers to your questions. This is by design, because the intention is that you check the site regularly (and answer other questions), not that you wait until you get a mail.
I somewhat agree with that, except for new users that post one question and checked the "notify me of new answers" box: they will never know that someone asked for clarification in a comment. You can support my proposal to send them mails for comments too.
