How about just ONE more sub forum? A practice dojo would be nice. That way people can practice the fighting system to know how exactly it works, because it is rather complex. You can have example fights as well, so instead of everybody being afraid to fight first, they can see how it is offically formed in the dojo.
So it doesn't mess up the experience gained thingy(yes, I am SO bloody technical) we can have it contribute nothing but be more for fun. Or perhaps we could let it give us minor experience, if it could be worked out. An all-nations-welcome dojo would be quite nice.
