Private - well that must be for sure, as through yesterday, I still have not be able to find anything on the net about even Edgar's passing. Of course, now that you have posted the information here, at least a bit of the details are "now public", or will be won't they! Dave Hilton's notice here of his death is online now too.
Relative to my "where" - the LIVING Moon Forum is where I would post the information. Edgar was at least known there, and he did receive a fair amount of bad press there from "one" who came there just to promote that bad press - I won't call any names!!!
I do appreciate everything you said about Edgar. I did only know him forum-wise - Alien Scientist and here. But I did have considerable respect for his forum work and his camaraderie, and his work toward trying to help the forum grow and succeed.
