I don't know when it will be shown but the taping is the evening of Oct 17th, it does say not to brnig anyone without previous concent by the station.
This is what the email says;
Thank you for signing up at 10tv.com to join us for a Wall to Wall show.
Your name has been selected and we'd like for you to join us in the studio for a taped show on Sunday, October 17! We'll also feed you and give you a free tshirt!
You'll need to be at the station NO EARLIER THAN 7:45pm and NO LATER THAN 8:00pm Sunday night.
If you are interested and are able to join us (must be at least 16 years of age), please reply to this email as soon as possible to confirm (WHEN YOU RESPOND PLEASE GIVE ME YOUR TSHIRT SIZE!). Once confirmed, your name will be placed on the Guest List for that date, and you will be emailed with more details. PLEASE DO NOT SHOW UP AT THE STATION WITHOUT CONFIRMING DIRECTLY WITH ME - YOU WILL NOT BE ADMITTED INTO THE STATION IF YOUR NAME IS NOT ON THE LIST. LEAVING A VOICEMAIL MESSAGE SAYING YOU'LL BE HERE DOES NOT MEAN YOU WILL BE ON THE LIST - YOU MUST SPEAK DIRECTLY WITH ME TO CONFIRM OR YOU MUST RECEIVE A RESPONSE FROM ME VIA EMAIL. EITHER WAY IS FINE - OTHERWISE, YOU WILL NOT BE ON THE LIST AND WILL NOT BE ADMITTED INTO THE STATION.
If we do not hear from you soon, we'll assume you're not interested and will offer your spot to another person. If you're definitely interested, but can't make it on this date, please email me back and request another date - AND DON'T FORGET YOUR TSHIRT SIZE!
CONGRATULATIONS!
They also sent another document with the rules and stuff after I confirmed, normal stuff though, don't be drunk or high, don't wear all white stuff like that.
Think they wanted the t-shirt size? :)
