Hi,
I would also like to know the answer to such questions but my guess is that people are going to ridicule you as thats what people are like on this forum : /
Firstly, they will say "read the forum and search for answers on here before posting."
Secondly they will say that your son will struggle to do will in this industry if he is not able to search for such answers himself instead of his mother doing the work for him. (which I kind of agree with).
Cheers
