Besides any event with Flossy in it is a better event from the start
I totally agree with that.
The reason I stuck to 9:30 is that it was the original schedule (this non-regular running of the "This Day in WWII" event is a stand in for the cancelled scenario), and I started to get some folks who registered for the scenario saying that they couldn't make it if I changed the time.
The regularly scheduled "This Day in WWII" events are all run at times that are good for Europeans (even when I have to run two events in a day to cover both US and Europe). I even ran the Milne Bay battle at a time that would cover Australia (although it meant me getting up at 3 am on a work day to do it). August's "This Day in WWII" is Battle of Britain, Eagle Day. It will run at a time that Europeans can attend.
