I am glad to see efforts to do classroom sessions.
Given the 24 time zones we have on the planet, perhaps I can suggest that
sessions like these be repeated once to handle timezones. My suggestion
would be for the principal presenter to present his/her stuff during
waking hours and schedule another to handle those whose waking hours are
I think it is wonderful that people step up and run classrooms, and as
recipients of these sharing, we should be appreciative of the effort and
let the presenter do it in their time zones.
