I've found mail servers to be much more friendly. This is due in part to
the restricted access, which requires subscription in order to post and
read messages. Someone will have to seek us out, and decide to
_join_ our "family". Newsgroups are open to all, even those who may not
share our interests, but choose to post non-relevant material.
Newsgroups are more prone to excessive SPAM mail. I see enough of this
on mail servers, and do not wish to see the mil-veh list ruined by this.
MY VOTE: Keep this as a mailing list.
