So I just ordered me a MacBook Air, my first Mac! I'm really excited and also nervous because it said that I have to sign off on it. However, it is going to be delivered next Thursday, and I will be in class. How am I supposed to receive this? Because additionally, as I am in the dorm, all mail goes to the mail room first and then I can go pick it up. Can my mail clerk sign it off for me? Thanks in advance! I'm just nervous about it coming and not losing it.
