Nice one. What an odd time to update. Overnight would seem a better choice......as long as it goes on, i don't mind.
I think it's so they can oversee the upload during office hours.
Why they don't just upload all the content with a specific forward-dated start date/time is anybody's guess... Presumably some technical limitation.
text chat is a must have function for skype more texts are sent in an hour then there are seconds in a day.
