I personally wouldn't just post recipies or information because I'm not an expert. I have tried and done many health related things but I did it to my own body and I always hesitate to give someone how-to info without the why, where and what for info. I am guessing that many people would rather send you to an expert than try and solve your problems. This is a health forum and sharing our experiences is great but with that sharing comes a certain responsibility. By sending someone to a website or webpage I feel I am helping to empower that person to take control of thier own lives.
Now if you have any specific paint questions I would be happy to send answers:) (Not to this web site though) I do know a lot about that area and I could tell you safe ways to do all kinds of paint things. What I am trying to say is that maybe people aren't comfortable giving out expert advice when it's not thier area of expertise.
One other reason I don't just clip and paste is I am very concious of plagerism. I wouldn't want to step on anyones toes or even hint that I knew more than I do.
I hope this helps you to understand. I think you will find this type of hesitancy the norm on most health related boards.
