Dr. Jack,
Some people receive their messages in individual posts rather than
grouped together in digests. The individual messages are distributed
by the listserve as they are received, so a prompt reply may show up
in the same digest as the original question. To recieve individual
messages instead of digests send the command SET LACTNET NODIGEST to
the listserv address.
