A self-described "devoted reader" has sent me a private message reminding me that the status of the US MR industry relative to Federal Do Not Call legislation is not "exempted." That would imply a specific exemption in the law which is incorrect. MR simply is not included. While operationally there's not much difference, the legal advantages of being not included as opposed to exempt are significant. My son the attorney no doubt would be very disappointed in his old dad. And thanks to the reader for pointing this out.
