I pre-registered and got an email saying that that the item (my registration) has shipped.

Is the ticket actually being mailed to my shipping address? Or is this just an effect of the shopping cart system?

Has anybody heard anything about this? I pre-ordered two tickets and am still unsure what that means?

Last year I didn't have to bring anything even though I printed out the order, I am going to use my smart phone if they ask for more info this year (other than my name)
