Looks like I didn't explain my self properly. Sorry for that. With sharing, I mean they can use my computer (in the store)when I am not there. But since I bought all the cd's fair and square I do not want them to burn cd's for themselves. If they like the music i've put on itunes, they should go to the store and buy the cd's just like everybody else (who is honest).
So can I disable the burn option or not?
