Mike,
It will be really great to have you in the core group for the summer,
and for your student to be involved also! Let me know if you can 'come'
to any of our (now-famous) virtual meetings (via speaker-phone and the
web).
Best regards,
- Will

Hi Will,
I would like to become a "contributing member" of the GSIM focus group.
I will devote 33% of my time this summer to this project. Due to my
university responsibilities, I will not be able to start until May. But
I will attend any meetings I can before then. I also plan to get a
student involved this summer.
Later,
Mike
