They can’t comment without entering their name and email address anyway, so is there a plugin for bbPress that will add that name and email address to a mailing list and allow them to receive email alerts of new comments to that post?
I am sure you know, there are plugins that do that for the WordPress comments, so that even commenters who do not have a WordPress account on that site can check a box to receive email alerts of new comments.
