What would be the best length of time, and dates, to hold the Symposium?
Catholic Easter is on Sunday, April 8. I know that US schools traditionally have the week following Easter as vacation, what about Europe?
I would suggest we hold the symposium for the two or three weeks proceeding Easter (ending April 20 or 27), which gives us a vacation week which is important, and it is early enough to avoid school and university exames, I think.
