Worth? Haven't you heard of the Connection-Oriented Test for Troll Detection, ISO 8686? If you're going to continue this marginal impression of a 14-year old with access to Mommy's computer, at least make your comments a reasonable effort for Saturday Night Live. And in the event that you are trying to insult me, may I suggest some less recently used epithets with more literary merit? Tufthunter? Descendant of ten thousand generations of unborn slime? Pointy-haired boss? PMS generator? And while X.25 is not on the CCIE lab, it remains on the written. > > > >""Howard C.
