This site uses StatCounter on our website to count the number of visitors to the site and to tell me whether they are first time visitors or returning visitors.  It also helps me to see which pages are the most popular and interesting to my visitors so that I can improve the site and make it more relevant.  It also helps me to see approximately where my visitors are coming from so that I can tell how wide an audience I am reaching.  It does not give names or addresses of my visitors or any other personal information.
I use this information only for the purpose of improving the site and its services. No information collected by Statcounter through this website is passed to third parties.
