OK that's fine, but how about the other issues? :)

It's not my job to ask 12 year old kids, it's yours :) But I'm curious, what sorts of questions do you ask them? You say you are on the phone talking to them, do you actually show them how it works in practice? Have you used well-known HCI techniques and vulnerable persons focus groups, etc. (1)? Have you approached children's groups for advice on children's rights and parental responsibility?

These are just a few things off the top of my head, too, that a responsible company should go through before developing anything to do with children.

BTW if you've done all this, put it on your website! Reassure the people who might want to use (or critique) your application! :)
