[plug] [admin-plug.org.au 12346] Re: Step rise in moderation emails

[Nick Bannon]

Hi, Harry, James! Let's get this out of our admin list - anyone else
out here up for helping us up our mailing-list-moderation skills?

We're running the latest Mailman2, so there's a lot of low-hanging
automation and tweaks we could do to the lists; but I suspect the
best move we could do is deprecate a couple of our less-used lists,
synchronise our settings across the remaining ones; and concentrate on
our public plug at plug list.

Nick.
