Good luck with this. The fact you won't allow members to raise money privately, or battle privately might just push people away though. :
And never allowed to leave? What if the member has to leave Gaia all togetehr, or cannot keep up with your little peace thing? Anyway, you may want to consider makign better rules.
And honestly, you can't kill someone on gaia, I'm sure you can in the battle system, but I doubt they will stay dead. >>;
