However, do you think it is possible that the website email info was spoofed?
No, I don't. Who actually expected Parham to answer queries, especially on a Saturday morning? (Which it was in Indonesia.)
Several people wrote to him; they got answers. At first, posters complained that Parham sent all of us the same reply; later, when others got messages with different wording, they complained about that too.
I'm entirely satisfied that the email I received was indeed from Greg (not "Graig") Parham.
