To allay fears of those who have received no notifications from Rhino post-purchase:
I received my Paranoid today, singly, apart from the other four releases in my order. I have thus far received no communication from Rhino, nor have any tracking numbers been added to my order on the website, though the order status did change from "Ordered" to "In Progress." The tracking number for Paranoid did pop up automatically in my Informed Delivery account through USPS. I was then able to add it manually to my UPS account to track the pre-USPS movement. I have no doubt the remaining three Quadios (plus the other CD I ordered) will be shipped soon, notification or not.
Be patient. Good things come to those who wait.
