As you know from the email I sent out when I moved this Message Board, a fair number of people have posted to it since I started it. I've actually received email from more people who have visited the various Andre Norton Web sites and thanked me for my efforts.

That's true, but those of us who enjoy her work still as long-time fans tend to get involved in other types of fandom, too. All things Norton are on topic for the board.
