Hi Eric,
      This is Arthur Chan, one of the current maintainers and developers of SphinxTrain and Sphinx3.  How are you?  I saw you answering one of the user's mail. Your knowledge of Sphinx's codebase and history will be very important for the things I want to do in furture 6 months.  Could you kindly contact me at archan at cs dot cmu dot edu?

Thanks,
Arthur Chan
