This appears to be a notice section on this site. I have discovered many well intentioned and caring people post their opinions with little or no knowledge of the topic being discussed. I have never advertised any sales or services on any site. least of all a small site like this one. Trudi has done a wonderful job piecing this site together to help people learn about water. I am sure this site was not intended to be another facebook or twitter social opinion site. So the "Notice Of the Day" is * Feel free to ask questions.* The answer will be 100% scientific based. Those looking for individual solutions to their own circumstances need only clarify. I have never advertised any goods or services on this small site. I find it helpful if you do not like or understand an answer just ask. No one should ever feel bad because they did not understand current technologies. Trudi made this site to exchange ideas and learn from those extremely knowledgeable in their respective fields. In case anyone missed the point of this "NOTICE"! Information is always free. Just like water, air, energy. The more you learn the less it costs.
