Your advice was very timely and thank you for it. But what made me mad was that this 48-year old hulk came into the forum just the other day, and he gets after this 17-year old who's just written a most precocious paper! It made me see red. But I shall hold off; several people contacted me and asked me not to get so agitated, that they would take care of things. Thanks. I owe you ;-)
