There have been a lot of contradictions in what Humble has had to say about MMS. Take a look at the MMS Debate forum (if you dare venture into those sharky waters!) to see the latest.
My information came via an email from my friend who operates the Minnesota Wellness Directory after he spoke with Jim Humble by phone to ask for clarification about how it worked. He had no reason to lie and has never uttered a single falsehood to me in all the years I have known him.
