Dear all,
I will be on a plane to Orlando on Friday (my birthday :-( )
I will be back Sunday.
Two options (which basically depend on the agenda of the kick-off meeting):
Either
(1) do it on Friday without me - Yury should be free..?
or
(2) find a time next week.
What is the agenda for the kick-off?
Paul, could you please change my subscription from "digest" to "direct". It
appears that the daily digest slows down discussion too much.
Thanks,
Jens
