This. Much agreement.
As a newer poster, but longer time lurked, I have noted occasionally posters in older posts who were frequent contributors but are no longer active. While I would expect, and hope, the lack of continued posting activity was not due to passing, I would welcome something which acknowledged posters passing to recognize why they no longer posted. That said, in conjunction with some other recent threads I do not know how readily that could be done without potential difficulties or issues. Just wanted to add I like the idea.
