Dates Submission: Submit no later than 11:59 PM (2359hrs) Eastern Standard Time, September 16, 2011 that was found on the "official contest site" link, my question is.. why does LL say the 9th, when the office contest says the 16th? Is the 9th when LL wants to know how many people want to partake.. or when the final costume must be designed by?
