How do I get a Digest subscription?

Hello,
This will be my last attempt & apparently no one is monitoring the owner's mail. How do I get a "Digest subscription"?

I am in the "users-lounge" at     
 

    http://postgresql.org/users-lounge/index.html

under Mailing List in the "See our subscription form for details", I select the 'our subscription form' link which brings me to
 

http://developer.postgresql.org/mailsub.php

It serves a form    " PostgreSQL Mailing List Subscription"
with a drop down menu  of all the available mailing lists
Radio buttons to Subscribe/Unsubscribe
    Receive mail? Yes/No
    Digest only?    Yes/No
and
   Input text field     email to subscribe
 

I have tried every permutation of email/diges options, and have not been able to get digest mail for this list, [GENERAL]

WHAT am I doing wrong?

Otherwise I'll have to unsubscribe permanently. Thanks.
