Greg, Thank you for the list!!!
I agree that 6-12 months after the second call, the disc should be donated or sold to support the time/effort/storage space that 850+ discs require. If I turn a disc in to DD it usually after I have called the person and let them know I was dropping it off. So their 2nd call is probably 3rd or 4th call.
Thanks again to DD for helping out with this.
and yeah...not a one was mine.
