I thought my ears were burning!

I can see both sides, but overall, I'd say a kids board would be a good idea. Without going into detail, there are many chat rooms on the net where certain types of people prefer to prey. I doubt a games site where the huge majority are adults would be much interest to them. Especially once they realise how heavily moderated it would be. A bigger concern is private messages, I like Scarlets idea of needing parental permission before an adult can message a child - and also parents should have to give permission before their kids can message adults. I'm not sure how easy that would be to set up though.
