Thanks to everyone for the dozens of emails and comments about the site. Most were positive, but some people noticed SQL errors which prevented certain address searches from working. There were also some Opera browser issues, and of course, typos.
The SQL errors and typos reported have been fixed, and I apologize for any inconvenience. I'm looking at the Opera issue which affects the display of the popups.
Please continue to forward to your friends and colleagues and use the "Contact Us" form on the site to report any other issues. Thanks!
