description:
Rip out the code that broadcasts talk requests to the local
hunt-players mailing list.

In this day and age it doesn't even begin to work: even if you were to
have such a mailing list locally, sendmail wouldn't expand it for you,
the addresses you got back wouldn't be talk-requestable addresses,
talk requests don't cross NAT or firewalls safely, talk doesn't
support ipv6, and nobody runs talkd anyway.

It doesn't make sense to try to replace it with some other kind of
notify scheme either; there might still be a multiuser machine
somewhere with enough simultaneous users that broadcasting something
akin to talk requests locally might make sense, and where a nontrivial
number of the users actually play hunt, but probably not, and if so
those users are likely to be better off using wall(1) anyway. Nowadays
games will be set up by looking for people in chat or by emailing or
texting friends.

Theoretically someone could set up an internet hunt metaserver for
finding hunt games, but that would be something entirely different
anyway and I doubt there's demand.
