I think the biggest problem is that WIS doesn't think this through beforehand.
There is no reason that they can't have mapped out all the seasons and know when they are going to fall, and what adjustments they may have to make. It would probably take one guy less than a day to chart everything out in Outlook and make some recommendations.
WIS should also have a schedule and be able to tell people in advance that they will be shut down on certain days, Thanksgiving, Xmas, etc. So in this case, maybe recruiting starts at 6 PM on 12/24, but the site is puased on 12/25, so 12/26 is the second day of recruiting.
