All you have to do is look at the calender.
July 7th (Fri) - Player Extensions decisions Due. Draft Order Set.
Beginning Sunday, July 2nd my work schedule is changing to where I'm working 3-midnight. I'm not going to feel like sim'ing at 1 am when I get home from work. So sim's will be done during the day, most likely sometime between 10 am and 2 pm GMT-5. So whereas the deadline to get dc's and changes in was 5 PM before, it will be midnight of the previous day now (i.e. for a tuesday sim, get things in by midnight monday night). That doesn't mean I won't accept things after midnight, just that it's not guaranteed after midnight. This is true for the Tuesday, July 4th sim onward.
That means it'll be today.
