	- the packet driver interface is what'd be needed, to use a
	network card with dos driver, to use a dos desktop for broad-
	band (still my longer-term objective) ?

	- o.k.  (i think i remember people (including richard, perhaps)
	IP using packet tracing to diagnose a problem a long time ago -
	but there's no saying they were using the dos suite to do this.)
	  hop check i do use, and it's still there in 03e.

	- many thanks: once i'm safely through this forced emigration,
	i may ask you (unless it'd be simpler for you to do a pplg_03e,
	as it were, using the work you've already done for pplt_03e); i
	have been using clockwork frog's view tsr whilst online to e.g.
	try and check a sender vs. my mailkill file, but it's not got a
	search function and it stops everything else: so if i take more
	than a few seconds, it kills the dialled-up session, and the
	phoneline drops.

	- both good; & so using the catch-all'll be a significant relief.

	- *nods*; but iiuc c+w've not mentioned in all of this that
	we should (rfc/use-for "should") *all* open a user a/c for
	postmaster, nor made it an existing user a/c by default - so
	the catch-all a/c default named administrator@ is the only
	a/c they can be (almost) certain we'll all have.

	- i just bunged an extra line for it in the alias file - and'd
	not got around to removing it, when it didn't work for the c+w
	forgery.

	- oh yes!  (though not absolutely everything by him): one of
	sf's all-time greatest humourists, _Dimension of Miracles_
	(or the extract in a year's best anthology, "The Story of the
	Creation of the Earth") is whence douglas adams inadvertently
	stole much of the early hitch-hiker's from, ideas and details;
	_Mindswap_ is better still; _The Journey of Joenes_ (_Journey
	Beyond Tomorrow_) provides further friendly assurance of the
	insanity of the world, and _Options_ is a little like _Mindswap_
	seen from the inside...
	  _Immortality, Inc._ is an exception, being of significant
	grimth and not to all sheckley-fans' taste; it's good and well
	worth reading, but not for light relief.
	  just about all of sheckley's short stories are humorous gems,
	including the a a ace planetary investigators series (recently
	run in dramatised form on beeb r7/4extra as "The Laxian Key",
	which is the title of one of them); all of his collections are
	worth grabbing, and you see any of them - few of them've seen
	reprints after the first uk p/b editions, so they're getting
	steadily harder to find - not just _The Robert Sheckley Omnibus
	(a kind of "best of", plus _Immortality, Inc._) (penguin_) and
	the beautifully-entitled _The People Trap and Other Pitfalls,
	Snares, Devices and Delusions, as well as Two Sniggles and
	A Contrivance_...

	- spotted in the queueue on the punt-3 cluster before i down-
	loaded this batch of news from the firedrake; my immediate re-
	action was "i'd better add a line to the alias file, first",
	before i realised what it'd be and quashed the automatic urge.

	- again, thanks for the work you're putting in on all this;
	let me know if you'd like an eye kept open for any of the
	sheckleys - or any other fantasy &/or sf, for that matter.

	- love, ppint.

	[0] - ghee!
