With the holiday, I didn't want to schedule a sim on Monday (today) like I intended, so instead we'll have a nice long period for the trade deadline, after which no more trades will be accepted for this season. The deadline is a day before the sim so the TC has adequate time to vote and to POSSIBLY have the time to reject a trade and get a new one re-submitted before the sim time.
So if you want to trade, get them in before Thursday at 2 PM EST or you will have to wait until next year.
