Janet, My guess is that NPF is a non-profit organization since most Foundations are. Organizations which are non-profit usually have to be incorporated by the state, at least in Calif. They also have to have an IRS number to be non-profit and have donations to them be tax- deductible. NPF hasn't, to my knowledge, charged or demanded anything in return for their literature. However, they do exercise their right to put you on their mailing list if you request something, and will send you their promotional material and information they feel is important. Our Parkinson support group is incorporated in the state of Calif. It was the first one done in our state. I am not in anyway affiliated with NPF except to have contributed on a voluntary basis as a writer to their newsletter and to be aware of the good that they have done in many instances. They have helped the Parkinson community primarily in myriads of ways while maintaining their own organization. I know what you mean...there's no free lunch. I, too, am a skeptic. Perhaps the only reward they are expecting is our unrequired gratitude in monetary form for what they are attempting to do for us. Bev 74/50+
