Huh. I actually never noticed that (not having come up with a For Children question).

It's not a catagory in the original choices but once you get through to the page where you write the question up you can swap catagories if you want (I figured out I'd put the wrong catagory in once so went to change it here) and 'For Children' appears as an option on that page so could people be creating questions for the catagory there?

They might be creating them there, but when the FC editors see them, we move them to the correct categories. Or rather, we do that now - we didn't at first.
