Hi Paul
Young master LT, ./., elite, or whatever, is no longer with us, he
just unsubbed. Irked, no doubt, that his queries got ignored.
Oblivious, no doubt, to the fact that he'd ignored responses from
Dana, Ed, Mike, and Bryan to his previous rudenesses ("Truth hurts!"
etc, LOL). Ah well. It's a pity, he's trying, and he came to the
right place. I wasn't the only one who referred him to the archive, I
hope he's managed to figure that you don't have to be a member to use
it.
Best
