I have asked this question a few times with little response.
Since the digest feature is now gone.
Would there be a way using something like the moderator notification feature to send a email to a mail list. With version 6.2 you have to add a member number as moderator. If you could just add a email address and use a mail list. Then anyone interested could subscribe to the mail list and be notified whenever somthing is posted on the forum.
