Okay then. Nice to know I wasn't finding anything because it wasn't
there to be found. :)

This was the place I was sort of hoping that 'once a day' could be
changed to 'once every 6 hours', but my rather cursory glance at the
code made me conclude -- nope, not here.

I can guarantee that this would not be a problem for our particular
user community. ;) Even if every one of us decided to passionately
wade in and post to the max on a huge-and-pointless flame war -- there
still aren't enough of us to provide a large load. But your point is
well-taken. The flame-war part is precisely why people want deliveries
to be once, or a few times a day. The belief is that people who have to
think about what they are writing -- as they only get one crack at it every
24 hours -- produce more reasoned responses than those people who are more
accustomed to shooting from the hip and then apologising later if they
turn out to be wrong.
Thus in the eternal 'give mailman 3.0 everything that we cannot do now'
discussion, a 'cool-down' period has just now shown up as a thing that
real users have been asking for, and which would have ended up as a
blocker for moving from 25 year old software to mailman -- except that
if I cannot convince them I know how to hack a cron job, then I am
just rubbish as a spokesman, and that's all. :)
Thanks very much Stephen. Always a pleasure.
