I simply cannot wait until this is in effect. When telemarketers do strike, I ask to be taken off their call list, to which I usually get some sort of mumbled acknowlegment and very little reassurance they will do what I asked. Some of them are very pushy and have even continued their pitch to the point of harassment, not taking "no" for an answer and even calling back repeatedly.
But I know everyone has this same complaint.
However one bad thing I noted about this registry is that long-distance phone companies are exempt, and AT&T is possibly the worse offender at my house. Oh well.
