A friend is involved with the launch of a new site: Doctors With Disabilities, for health professions students and health care professionals. It's wiki-style, hosted by the Disapedia, a disability wiki. There's also a forum for messages. Diabetes is definitely included.
It's not just for doctors and med students; those in allied health professions are very welcome. The focus will be on sharing tips among students and people interested in the medical field and those in practice. Check it out!
