Advise author of new comment

[skoegler]

I want my authors to respond to comments but they don't get announcements (like I get as the admin) when new comments are created. I know I can add a string of email addresses to the announcement function, but only want to have the single author advised when a new comment is created on their article.

Does this function already exist (I can't find it). If not, I would appreciate adding this.
Thanks
