Parts of the announcements I made earlier in the week were designed specifically to assist in those issues--to assist prospective physicians to obtain the information, get connected to the right people, and then be certified if they meet our standards.
I think I'll leave it for some experts to go into a little bit more detail on that.
Frank, are you prepared to talk a little bit about some of the details?
