I called the main switch board and was connected with a voice mail box for Edgar Bronfman. I left a detailed message explaining our position and asking Warner to consider dropping DRM in favor of unrestricted digital files.
In the process, I discovered that the VM box is 4400. If you call direct to 4400 you get one of Bronfman's assistants. I spoke with Frankie, and she was very nice. She suggested I email her and she would make sure that my comments get to the right person.
