They were warned that their late submission would reduce their opportunity to get votes. There were 13 submissions when I voted, so if it came in after that, then they can't get a vote from me.
I like the way Dave handled it. I don't think it's totally important for the anonymity to be strict. If the late submission turns out to be the best and they don't get crowned due to timing, then that's OK. Because, they still shared their project file with the rest of us which is why I'm here. To learn from others.
Maybe if, in the future, we can talk some vendors into donating prizes then we can worry about it being a little stricter about the rules. But, until then it should probably stay flexible.
Just my opinion, of course.
