chti guillaume,
First of all, as an "old timer" [NOT!] around the forums, please allow me to welcome you.
Your input is very interesting and I appreciate your thoughts very much. I will need to study your ideas carefully, as I'm not confident that I understand all of the relations you've put forward - yet.
Regardless, it's very kind of you to respond and I'm particularly happy that you chose to make this topic the first of what I can only hope will be many future posts.
Very best regards,
Tom
