For some reason I can't find a plug in which automatically sends an email-notification to all people who have responded to a post already once somebody posts a new comment.
Say you have two comments on a post already and a third person makes a comment. On that moment, I want the first two persons to get a message automatically saying that a new comment has been made. In that way responders can follow the discussion without checking the blog all the time.
Ofcourse I prefer a simple, stable plugin.
Anybody with good experiences on this?
