dude that is awesome. Similar story happened to me at 15, and
http://www.jamn945.com a local hip hop radio station left anonymous access open and I went in and changed ever picture to something I made saying a promo for my hacker website. Then someone from netsol called me because I had just registered my hacker domain and he said "if youre going to try and hack, hack smaller pages not corporate websites" because I tagged all over this new website that I hacked them. Good read!
