Liability for participating in or running an alternative medicine internet forum.

I'm a member of an internet forum about a specific mindbody approach to chronic pain (and other symptoms). The approach was first discovered by John Sarno, MD, who called the condition that he was attempting to treat "TMS."

People regularly pop up on this discussion forum and ask whether what they have could be TMS. Frequently, many people will respond that it is "just TMS" and that they should stop worrying so much about hurting themselves and think about what emotional issues might be causing their pain. People often post about remarkable recoveries that they have made.

The address of the forum is http://tmshelp.com/forum/forum.asp?FORUM_ID=2 . It has been around for about a decade.

By participating in this, am I exposing myself to legal liability? Is the owner?
