Absolutely certain. Unless of course this is a trick question. WHich I
doubt. But thanks for everyone's help!

How ironic.

sometimes i do wonder just what motivates you Adam - among
your peers - to throw around your weight with such lame snipes.
The "Sheik of the Usenetz" mirage, spread from alt.config, no less.

YANBT...i have thought the same as you are thinking however the
weight of evidence does not add up, so far.

yes, "wds" is quick to feed Derbyshlre trolling:
Message-ID: <igqpef$ft$1@panix1.panix.com>
Message-ID: <igjhek$r2c$1@panix2.panix.com>

yes, same TZ and a lot of style similarities.

but equally so "wds" leaps to with comments on the nutty posts from
the sciFi groups giving head to the fantasy types like:
http://al.howardknight.net/msgid.cgi?ID=13...

add to all the fact "wds" predates Derbyshlre in (paid) subscribed
posts and I reckon you can rest easy. "wds" is just another of the
chain tuggers long established around the usenet. and he knows about linux!
nobody can throw the first stone in that case eh?

you see Adam, unlike you i build my paranoia from the hand of the people who
post it. I do not guess, I find and link to it. you might try doing that work and
your head will rest a way lot easier?
