NO, NO, and... NO! I wouldn't risk it at school. FC tracks you by the IP address you signed up with. If, by chance, someone else in the school was on FC at school at the same time you were, you would most likely BOTH be deactivated. It's one user/account per IP address. If anyone has EVER used the school's computers to sign up for FC, you're risking your account. (It's the same thing as any other public/shared computer. It's also in the Terms of Service Agreement!)
