The spam-to-value ratio in this email group is so high that I must
leave it. I tried contacting the owner of the email group, Philip
Bonhard, and asked him to reconfigure it for greater spam-catching,
but received no response.

I suspect now this is an orphan group, with the moderator possibly
having lost access.

Of course, I am still interested in recommender systems. And so, if
another, well-moderated or spam-protected mailing list is created, I
would welcome an invitation.

My high regards to you, dear reader, I remain,
Dan Greening
