Dear Nerd, (Steve Winick),

Thank you so much for your learned comments earlier. I have had to wade through so much po-faced commentary in this thread that I damned near gave it up in despair.

Thanks also to Brian Peters and Greg Stephens for equally learned and measured analysis, not forgetting Richard Bridge, and the acerbic but valuable WLD's remarks.

Bryn Pugh - with regards and respects.
