Bry: i have to admit that I've edited/deleted some things you really wouldnt want a child to see.

Well, that's very subjective. What you find "unsuitable" for a kid I might not. And I might find things "unsuitable" for a child that you find perfectly normal. I've lived on both sides of the pond and what's considered unsuitable for children is quite different. Nipplegate was a big scandal in the US -- exposure of a nipple, specially if a child could see it -- is considered shocking by large groups of USians. Half of Europe is still laughing about it. OTOH, Europe frowns upon violence much more than the US. In Europe, people generally don't own guns. In the US, people have different ideas of freedom.

If you were to moderate a board for teens, or younger kids, how would you moderate? American style? European style? Asian style?

I think having a moderated board for teens/kids is just asking for trouble. Nor do I think it's something that ought to be on a games site.
