Got the recall yesterday (fri, sept 17). I was only told about a nov 1 class. I did hear the rumor (not from any official at NK) of a possible oct class and that if they could put it together, it would be in addition to the nov 1 class. Contactually I don't know for sure, but I'm guessing that the oct class would be optional, and as long as the nov 1 class stays intact, there would be no violation as recallees still have the option to get into the nov 1 class.
