I came to this post first, since it is first in line on the Index. It was confusing to me in the beginning, too, as to what these sections are called. As far as I understand it, the whole thing is a board, the "grouped" parts are categories, and each separate "section" is a forum, so you are correct to call it the "Paul forum". I guess it would go like this: "On the Paul forum in the Beatles category of the BNE board...."
I noticed with this John video, at about the 59 second mark, his eyes look very Asian.
