I have no time to pull out the links but I'll back Koo here, and confirm that on at least two separate occaissions the landing page on two of his last couple of podcasts/conference calls showed 'Dr. Donald McCaffrey'.  I personally believe this was some sort of mistake/assumption, unless he has been given an honorary degree that I don't know about.

I think that 95% of companies like Resverlogix are lead by a Doctor so it may be that the host of the conference call simply assumed he had this credential when building the landing page.  But I too saw this reference with my own eyes (and immediately didn't believe it) LOL.  Sorry Don.
