I think Gordon is right that Jocelyn reads the Mark Twain Forum, so she
may receive your message through that route. She's the author of, among
other writings on Twain, a 1998 book titled "The Jim Dilemma: Reading
Race in Huckleberry Finn"--published under the name Jocelyn
Chadwick-Joshua. She's also been active and effective in arguing
against censorship efforts directed at Adventures of Huckleberry Finn.
