This is just an idea, but you might want to think about holding the King back for a while when the server comes out of beta. I suggest holding back King for about a month to give all the clans a fair race to the top. That way, during the first month people can build their clans. Also I am sure clans will playing constantly so that they can get a chance to vote. This in my opinion will create some great competition and a chance for people to build strong clans. The whole king system right now throws money and power out of whack.
About people taking part in beta. I can understand why nobody wants to waste their time in beta. The only thing I can think of that will give players (who don't understand the importance of working out bugs before releasing code ...wait is bill gates playing now?) an intensive to play is some sort of exp boost for beta testers when the server comes out of beta, scrolls, premium whatever.
Great job on the server everyone!
