I'd agree with BM, it's not for PPRuNe to hold some sort of secondary register....it's not practical and doesn't add anything to safety.
Often, just like the real world, a lot of what we paste is "opinion" and we (me included) are often peer reviewed, quite effectively. Those who follow this forum, are likely to be able to sort out the wheat from the chaff.
I expect that the guidance from our regulating bodies can be circumnavigated to everyone's satisfaction, although we may have to a little more "wooly."
For example: "You've got supraventricular tachycardia" may be replaced by "I wonder if your cardiologist has considered supraventricular tachycardia"
Or "take ibuprofen" could be replaced by "ask your pharmacist about ibuprofen"
I know.
