BB, forgive me, I didn't grasp your last comment to me, so I'm just requesting clarification.

(Incidentally, I read elsewhere you're leaving mudcat. I hope it's not true tho' naturally I'd respect your choice. You have so much of interest to say.)

It's just that you said this is not the thread for my question. Please redirect me to the right place, tho' if you could say why this is the wrong one, I'll be in your debt.

Best wishes
