It's been something like 20 years since I last looked at talk and
wall, but don't the users have to take some action to allow these
to work (or is it that they have to to prevent them from working)?

``A Democracy cannot exist as a permanent form of government.  It can only
exist until the voters discover they can vote themselves largesse out of
the public treasury.  From the moment on the majority always votes for the
candidate promising the most benefits from the public treasury with the
result that Democracy always collapses over a loose fiscal policy, always
to be followed by a Dictatorship.''
