Half a thank you, Nerd! ;) Yes that is what I said. Interestingly, the OED defines trolling as "posting on the internet intending to provoke a response from the reader by containing errors" {NB: that definition contains a slight paraphrase, but no distortion of meaning. Just in case anyone might wish to accuse me of lying again!}

Insults, even failed ones, don't enter into the argument. I can spot a troll when one turns up, & I'm occasionally guilty of troll-baiting, I confess. I have apologised to Greg for any spoiling I might be guilty of in this thread, but Mr. Gibson's some threads are worth exterminating, in this context, says it all, I think!
