That last idea seems the best to me. If we all take the theme that came after ours, that would be a pretty fair way to handle it. We'll have to wait until we're sure that everyone who is going to participate has submitted their theme, of course. So far I think that just means we're waiting for Austenite. Unless someone else posts to the thread stating their desire to participate, we could just assume that Austenite will be the last one and begin as soon as he has submitted his theme.
How does everyone else feel about this? Any objections?
