You are correct in that it doesn't matter until we find his name on a list, if we ever do. And so far, in every instance where someone has claimed to have proof, the individual in question disappears back into the woodwork, never to be heard from again, when I ask for the information I would need to obtain and examine for myself the alleged proof.
"Some years back there was a lady on the Bradshaw mailing list who was just about as good as you but she was more strict."
Someone more strict than I've become in these last few years?
My mind boggles, cousin.
I'd surely like to re-incarnate the lady and see what she could accomplish with the first hundred issues of my 'Abernathy Problems' file!
