Good point, Thelma! And Chemar, I like the viewpoint you expressed, a nice balance. We definitely don't want to be diagnosing, but we do want to offer our own experiences, helpful sites, suggestions, insight. Otherwise we become no more than a shoulder to cry on. Which is good in itself, but if I've got a problem with my MG, I not only want a sympathetic ear, I want to know what others who had a similar problem have found helpful.
I feel I've got enough smarts not to blindly accept the diagnosis of anyone on this site, but I do agree that not every visitor will understand the dangers inherent in letting a layman diagnose their condition and treatment. So we do need to be cautious in how we word our suggestions, our experiences, our information. Not "Do this!", but "For what it's worth, this worked for me."
