It was brought to my attention in one of the leagues that the trading deadline is week 6, which was changed a couple of years ago in the NFL but never got reflected here. I have changed the logic for all leagues to be week 8 (I made the change today to prevent the leagues who were between week 6 and 8 from having trades turned back on suddenly, but allowing the leagues who had not yet reached week 6 to take advantage of being able to trade through week 8).
