I use this for looking up the doctors that I find, to see what others have to say about them, reviews, etc., and you do not have to join:
http://www.vitals.com/

i also use this site for doctors and to look at comments that people have left. i have left some not so favorable comments on this site because of the doctors and nurses that i have came across dealing with the anal fissure..

I think it is a good thing that we give our opinions. I too have put up both good and bad experiences.

I've been using ratemd.com.
You need to remember to change the country first if you are in Canada, but then it is pretty good. It does UK and AU etc too.
i will cross check with vitals though now that I know about it. THanks!

I use them both, workingonit. I wish more people would mention the doctor's name when they have not had a good experience - or when they have. I believe in doing so.
