I'm a bit late, but there's still two days to go. According to the few of us who noted our availability on doodle any time except sunday is green.
So how about Wednesday June 8 at 5PM GMT/UTC? If there are no objections that's when it's gonna be.
EDIT: Date changed to Tuesday, June 7 at 9PM GMT/UTC, everyone will be notified in advance. See below.
