D.C....funny you should ask. I just called the transfer agent yesterday to transfer my shares from my online account directly into my name (I want that bullion!!!.) The name of the agent is "Signature Stock Transfer" and their number is (972)612-4120.
For others that are interested, it is not a difficult process. You have to fill out an outgoing DRS (Direct Registration System) form, which is very straightforward. I was told that the whole process takes between 5-7 business days, and the stock certificates get mailed directly to you.
