You have the same IP address as Jimmy James, who asked to have his account closed, and list yourself as living in the same city. You also write like him, pointed out he disagreed on the Lennon/Harrison you posted, and are going after him.

BTW, generally the only ones in autographs that ask about credentials are dealers who sell forgeries. There are no colleges with handwriting courses that I'm aware of beyond a few that have courses for forensic document examiners, which is a whole different thing.
