Rootdown is a fun website for acupuncturists, TCM students and TCM groupies. If you're an acupuncturist or in school, go ahead and put up a profile! It's like Myspace or Facebook for TCM, except there are also resources like herb info, acupuncture info, et cetera. The resource aspect is similar to Wikipedia, in that you can add new information to existing entries.
Professors at TCM schools also have profiles! Take a look at Dr. Yue-ying Li's profile. You can also post or buy online CEUs!
