I think I got it, by George. Great explanation. I would love to have read it along with some illustrations drawn by Priscilla Gilman. You two would make a great team in writing a guide called XMRV Made Easy, or Endo and Exo Illustrated, or something like that. Anyway, good job George. And for those of you who haven't already, you might like to check out this website.
This is great, gracenote! I hadn't seen it before.
