Whilst credentialling all the medical posters on the forum may seem like an attractive option to you, it would be all but impossible to implement. There are advantages and disadvantages to an anonymous forum, and anybody can claim to have any qualifications. I am certainly not in a position to go around confirming credentials with worldwide health registration bodies. This, in part, is the reason for the disclaimer at the top of the page.
For a trained person, it is pretty easy to pick who the untrained providers of advice are, but this may not be so easy for the layperson. We do our best to provide a couter-argument to the more "out there" advice, without trying to stifle discussion too much, but this is not the place to get definitive advice on health issues.
We also try to reduce the amount of direct recommendations of particular practitioners. Being an anonymous forum can lead to a real skewing of perceptions in this regard. Indeed, there has been at least one instance of a medical practitioner posting on this forum under several usernames giving recommendations of his own practice!
It would be a real shame for this forum to wither because of legal practices in individual jurisdictions, so please keep the discussions at a level that you are comfortable with, and which don't expose people to un-necessary risks.
Cheers,
BM
