When do I worry about taping tickets?

Still haven't received my official ticket for the October 18th noon taping (and audition). Should I be worried? Or should I wait another couple of days before worrying? I'm committed to the travel times, so I'll show up anyway, but it would be nice to have that official stamp of approval.

gs, whose worrying is a genetic trait

Might as well wait a couple days before worrying, even if today is the two week mark. Unless you enjoy the worrying--then commence immediately.

I requested a ticket for Friday, Nov. 2 and never even got an e-mail response about that. Now that date has been removed from the ticket list, so I guess they've filled up.

I never got a ticket the last time I went, but I was ushered right in because my name was on the list. I did receive an E-mail confirmation, which I printed out and took with me.
