Yeah I'm having issues with my availability as well... just due to the timezone difference of being in Australia. I might also have to end up auto drafting, which is something nobody "wants" to do... but it may be unavoidable.
A quick bit of math indicates the following for me:
Wed 28th - Unavailable due to work between 6pm EDT and 4:30am EDT following morning
Thu 29th - Unavailable due to work between 5pm EDT and 3:00am EDT following morning
Fri 30th - Available between 5pm EDT and 9am EDT of following morning (except for a block between 10pm and Midnight EDT)
Sat 31st - Available between 5pm EDT and 9am EDT of following morning
Sun 1st - Unavailable due to work between 6pm EDT and 4:00am EDT following morning
Mon 2nd - Unavailable due to work between 6pm EDT and 4:00am EDT following morning
Tue 3rd - Unavailable due to work between 6pm EDT and 4:00am EDT following morning
Wed 4th - Unavailable due to work between 6pm EDT and 4:00am EDT following morning
Friday the 30th and Saturday the 31st being the best days for me, both of which are Not Open for one participant. So it does look like I might be auto-drafting.
