To Adam Spark: I really like the new features in the commenting system whereby one can mute posters. There will always be trolls whose only purpose for posting is to attack others who do not agree with his or her views. A public discourse is only as good as its civility. The only thing lacking is the fact their is no legend for the color coding by poster tags. A look at the link that explains the new system does not give any informative n on this. Great job!
