>Do you propose to spell things out for people who did not read what I >spelled out for them? ;-) Yup. Sometimes rephrasing, reminders, and even repetition is essential to essential education and clear communication -- which, I believe, would be the goal here. Feel free to correct me if that assumption (clear communication) has taken back seat to some other goal. And if you'd be so kind, while you're at it, do please reveal that higher goal. --tom
