I supposedly am on the "Do Not Call" list. I've had the same phone number for years and am unlisted. I also have caller ID, and occasionally I get a call from a number from out-of-state and they never leave a message. Do any of you that have caller ID and have not answered when you don't recognize the number, and know it's not anybody you know, think you may have missed out on a prize-winning call?? Is it true that there are companies that do not have to notify you by e-mail when that's how you entered?? I never give my number if it's optional, but if it's a really good sweeps and they demand it, I will. What do you think??? Thanks, J.
