Apparently it is illegal for children under 13 to give out personal information without parents permission...
A few websites have been fined because they let under 13's register...
If you don't believe me, google search it (I can't put in a link coz it keeps making the whole post invisable (its as if they dont want anyone to be able to go to the link so they can fine people))
I bought this up just in case this apply's to us... And if it does, what to do?
