As I don't think the challenge will be accepted by Joe, perhaps we can do something different.

How about a question and answer session? One question at a time. Very simple, I will even give Joe the first crack.

He can ask me a question about early RMK
Sheath identification, then I will answer as breifly and concisely as I can.

Then I will ask him a question, and he could do likewise.

No editorializing, that's what has gotten us in this long, drawn out mess in the first place. Question, then answer, followed by the next question in turn

Who knows, maybe we will get somewhere with it.

What do you think Joe?
