As my question mark indicates, I was unsure whether "Niman" on the board is the famous Dr. Niman. Have you been able to determine that the poster is a different person?

Well, unless the poster "niman" chooses to reveal him/herself more forthrightly, it can't be said that this is Dr. Henry Niman... but the poster seems to be knowledgeable about the topics discussed.
