Just a quick shout out to the subscribers who have joined us in the past several weeks.  I hope you find this site interesting and informative.  You can help by replying to posts with your comments and questions.  Don’t be shy … responses help me gauge what readers are interested in and provide feedback on points where I may not have been clear.  A straight lecture format would be boring.  Above all, interactive discussion is what can truly make the site rewarding for all of us.
