Slightly off topic, but there's a radiography wiki that's been running for a bit, and I check on it now and then to brush up on things I'm unsure about. Sure that someone could set up an EMT one? Course it would need a bunch of people willing to contribute to it, and probably wouldn't be officially recognised as CPD, but could be handy? (the radiography one's at http://www.wikiradiography.com/ in case anyone wants to know...)
