I don't recall ever posting to this person, Jean S says she/he never posted to this person until this thread, I don't personally know if EGPWS ever posted to this person until this thread and this person specifically said they were leaving because they made a promise to their family and then continued to break that promise.
I have no reason to not believe them, so that is...in my opinion...the reason they are leaving.
They are the one who invites ridicule by posting an opus. Everyone knows Opuses meet with this type of response.
