E-mail your PO address to me (kenhowell1931earthlink.net), and I'll send you some material to study that'll do more for you than I can.

For one thing, this isn't a subject that I have the time (right now) to dig deep into -- which I'd have to do, to do your question justice. It's not something that I know much about, so I'd have to study it long and hard. Since you're more deeply and immediately interested in pursuing it than I am, I'll leave the studying to you until I can get into it later.

"Good enough" isn't.

Always take your responsibilities seriously but never yourself.
