Why does this have to be so confusing? ... You have to submit your info and register a friend, then the friend has to do the same before you'll both get your shirts? But the form looks exactly the same when you sign in as the friend (from the link).
.... seems odd. The first time I registered my hubby & one of his 'geek' friends, I entered all their info in all the fields, then thought maybe they wouldn't get it unless the top field contained hubby's and below info friends, and vice versa, so that it looked like they replied to the mail.
Getting a free T shouldn't be this complicated. I wonder if any of us will actually get this. (LOL, I wonder if we'll get 5 of em -- I did the main thing 2x and then after submitting my hubby's info for a 2nd time, I realized I submitted the wrong size & redid it. LOL. I doubt it'll happen, but who knows.)
