Your post reminded me of some old threads--posted by providers or forum friends--about members of the forum who'd passed. There are probably more than this, but here are a few I dug up:

Nice to get a forum send-off like that, but I suppose many more posters have left this earth without any of us knowing about it. There are certainly some who have left the forum, if not this earth, who are missed. Maybe that's the more important thing than knowing if they're passed on.
