This weekend is booked. I'll possibly have time to make the trailer on Thanksgiving weekend, next week. If there's too much I have to do, or (this is very likely) it takes longer than that to finish it, I might have to say it won't be done until after finals, past December 14. After that date, I should have no obligations. If the trailer is the last step of Greenlighting, we should see it there by Christmas.
