    Serge,

    I have been studying Mandarin since 2004. I own several books and CD
    programs. I think your approach is so effective and efficient. I listen
    to your podcasts on the way to work every morning. I’ve learnt more with
    your podcast than any other method.

    Thanks and keep up the good work.

    Best regards,
