Xbox Live, Making new account?

Question

I want to download a Saints Row 2 trailer, but i made my account my actual age(13). So it wont let me download rated M content. My parents are ok with it. This is my first month on xbox live. I'm on a free gold trial. Is there anyway i can make a new account and what are the disadvantages of doing it. Also i heard that i could make a silver membership with older age and download things(rated M). How do i do that? Please answer both questions.

Answer 1
