I learn from Dr Adrian Midgley that the medical wiki, Ganfyd, has gone live with the message:
"Welcome to ganfyd.org - The free medical knowledge base that anyone can read and any registered medical practitioner may edit. Ganfyd is a collaborative, creative commons licenced medical reference by medical professionals and invited non-medical experts. The site is based around the wiki format, enabling true sharing of knowledge. GANFYD was initiated by a group of doctors who use Doctors.net.uk (AKA Ausdoctors.net) to contribute their knowledge and experience to the commonwealth. Ganfyd is an old medical mutterance whose meaning is known only to the initiated."
Btw ganfyd means "get a note from your doctor" and I think is GP-speak for basically healthy folks looking for sicknotes.
