Hi, does anyone know if you can use Skype for such calls? And would the number work from overseas or is it a kind of US only free phone number? Even if all Lipkin does is to explain how his research is going, I reckon it is really significant that the CDC have asked him to speak. In the not too distant past the idea of the CDC having someone like him speak, someone who views ME/CFS as a physical disease, would have been unthinkable. So even if we get no substantial news from Lipkin, I think this is really quite a turn around for the CDC.
