Hey, I know this isn't the official point of this mailing list, but I'm working on something related to the paper mentioned in the subject (by Nathan Charles). I'm trying to find more information about it, but unfortunately it seems that Nathan has left York. Does anyone know where I could find him? -- Hal Daume III "Computer science is no more about computers | hdaume@isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume
