There is a thread going on in the private pilots forum regarding a guy who had a heart attack and is wondering about getting his medical back!
One poster stated that he was a cardiologist and gave advice based on that fact!
Many others including myself made opinions which could be taken as gospel.
The problem here is identifying who knows what they are talking about and who doesnt.
The obvious solution is that PPRUNE attach an emblem to the poster who is confirmed to pprune as being medically qualified in the same way as they attach an emblem to a moderator.
In that way pprune know the identity of the poster and qualifications of that poster while their real names are secret in the forums.
With something so important as this thread that move is vital?
