Well, if you can make these long Days interesting, the better, because I am somewhat worried they might be pretty long and silent. But whatever way you wish. Originally, when I just skimmed through the thread, without reading properly the rules, I caught myself later during the day thinking how are you going to do that, and since I was not by the computer, I started to imagine possibilities and I came up with one conclusion, which was quite different from the one you present here, so I may as well save it for some game of mine.
But let me say it just for the sake of saying it - if we discounted Day 1, then every other Day people could vote for everybody regardless of timezone, because they will have some basis for trusting or not trusting them based on their expereince from former Days. Of course, I will have more current posts from those who are online by the start of the Day, but still I should have enough material from the others, too.
But that's just a comment.
