I thought since most of us are required to have a number of contact hours every year either for our jobs or licenses that we could share any free courses we know of. Here are a few I had saved:

http://www.cdc.gov/mmwr/cme/conted.html ~ though the CDC on this website you can take a ton of ID-related courses all for free (and ps they are not graded so just go right to the test) - BUT - make sure you click on "CNE" to the right of the course titles and take that test - it gives you contact hours - the other links give you a different kind that are MUCH less contact hours. You do have to register first, but it's all free!
