Dear Martin, Jason and List

First, Martin, I love your highly spirited answer to Jason.
Jason, as Martin says (and respects you)... you both should smoke
the "peace pipe"...

I am following this list because I love meteorites,
although I am barely buying any... maybe I will in the future.
(I love pallasites... but sooo expensive...)

This is a great back and forth exchange which gets to the core
of some really technical but real aspect of dealing with classifying,
selling etc...

So... hope you solve your momentary "quarrel"

Cheers
Michael B. (a meteorite fan from France)
