Tony, regarding your request for an email address for someone who could answer a few questions, your best bet for this kind of information would have been Ship of Fools...but if you read his recent farewell post you'll realize he has suffered a TIA and his memory may not be as accurate as it has been in the past.
Next to Ship, I'd say Evenkeel might be your best bet...you can probably find his email address on his forum profile...or PM him. He is still active, but not as much as he was in the past.
Other than that, a couple of long-departed members come to mind...but I am not too sure they would welcome any inquiries. One of them experienced some difficulty making a moderator happy, but the other just seemed to fade away. What a shame...he was VERY knowledgable! We seem to lose a lot of valuable members to "attrition", so to speak.
Sorry I couldn't be of more help
Cheers to you for embarking on this endeavor, and good luck! I'll keep you in my prayers...
