Actually, Charlie interpreted the original question correctly. It would be
a bit much to notify subscribers when there was no digest. Once I got the
digest-timing issue settled, I was going to recommend to the subscribers
that they check the archives if they were concerned they had missed
something, much as David had suggested.
BTW, the reason that I was trying to set up a regular digest-delivery is
that after managing Listserv lists for years, I was hoping to carry over a
digest feature that I liked. On Listserv the digests are generated when
they trigger the size limit, but there is also a daily default
digest-clearing time as well. It might result in a small digest, but no
one seems to mind.
