Drat .. been sending message to the group from the wrong email ... so have been bouncing ....
My feedback on the date.
If just the Sunday then in Europe and Asia it means Sunday night and very early Monday .... and therefore residents in those time zones are unlikely to stay up.
Ummm was going to suggest split timing to help with worldwide access .... plus not such a continuously long day for the Americas .... and mor time to do the weekend chores.
S.L. Times
Saturday 5pm to 9pm
Sunday 5am to
10am
But looks like everyone going for Sunday ....
p.s. ... to help with Internationalisation .... it is helpful to not mention the seasons ..... "Fall" (Autumn) is the other end of the year in the southern hemisphere ... just a suggestion
