I am a member of working group 1.
My home page is here: http://web.mit.edu/~axch/www/
I volunteered for this working group because Scheme has made my life unbearable. Scheme is so bad that I can't bear to work in it, and yet Scheme is so good that I can't bear to work in anything else either. For half of my (admittedly not very long) career, Scheme's uniformity and elegance have given my mind wings on which I have soared above the highest peaks, but Scheme's balkanization and non-interoperability have trapped me in the deepest dungeons. So I hope that I can contribute to standardizing the right base on which a garden of portable libraries can blossom.
