EDIT: Looks like they ran out of subscriptions already.
My previous free Macworld magazine subscription recently expired, so this is some good timing. It's like that time I was about to get beat up behind the bleachers in high school and then the gym coach showed up. How did he possibly know to appear there at that exact moment? It might have had something to do with me screeching like a little girl, but I prefer to believe it was destiny.
