I also happened upon a great reference in the FAQs for a counter and have installed it on my site today.  It is very detailed in that you can view a report that shows you who logged into your site, from what city and state and what service provider.  It will be pretty exciting to see the confirmation that people from around the states, or even around the world, have access to my silly little site!
