McGrath, here is the ideal opportunity to use CH and Mudcat synergistically... by laying out a thread here (with the right links to CH material) discussing the differences you are thinking about. When the thread is nicely browned, we can send a link to it to the CH folks for their continuing edification.
Be sure to also include, if and when sending them the link, a codgerly pic of yourself (just kidding) so they will know you are one of the great masters.
Amos, they are looking for pix of the missing masters over at CH; I think I will pick a good name off their wish list and send in yours for it. Any preferences or shall I go ahead and choose?
