I think most people are missing the point. We're not discouraging new recruits. When you deadbeat right off the back in round one, it messes up the flow of the game. I'm not saying this is the end all be all solution to the deadbeat problem. As long as there are rules, there will always be those who exploit them. This is just to help move the games along.
You still have your 3 missed turns, and if you get kicked out of the first round, go join another game, what's the problem?
What if we said that if you get kicked for missing the first round, you don't lose any points? That way if it's just some new person checking out the site, and after a few games they decide they want to stay, then they're not at a disadvantage.
Ideas!!! Don't just say you hate the idea because it's not going to fix the problem. Judge the idea on it's own merits.
