Gerwyn, It was known in 2001 that Wessely was an adviser to PRISMA and member of their Supervisory Board. I have provided two reference sources for that. In 2001, Hooper, Williams and Marshall published "What is ME? What is CFS?" In 2007, Hooper/Williams submit a document to NICE in which they make a statement for which they provide no contemporary supportive evidence. Instead, they give the URL to their own document of 2001. The 2007 document is therefore not a good source for a contemporary reference in support of your claim that Wessely is an adviser for PRISMA. You have an LLB - yes? Surely you can accept that. I don't care who wrote the 2007 document. It does not provide a reference for your statement. So the problem is, not that I am looking for something that cannot be found but that you have made a statement for which you cannot provide supportive evidence. Instead you ask me to rely on a document from 2007 which, itself, quotes a document by the same author from 2001 but provides no new source to support Wessely's continued role as an adviser to PRISMA. And then you tell me that I have not read your answer!
