AbigailII: what Nothingness means is that his opponent waits 2 weeks before moving. I've played Nothingness often enough to know he doesn't wait 2 weeks. If your opponent waits 2 weeks it's impossible for you to play more than twice a month and there's nothing you can do about it which is very frustrating indeed.
The problem is that if it's in the rules, someone is allowed to move slow. You can ask your opponents if they want to move faster, but they don't have to.
