CheckersUSA.com site closed

The venerable CheckersUSA.com site closed its pages after 25 years of service.
Actually, it started in 1996, under a different name, for the AICS (American International Checkers Society), led by Warren Williams and Jack Birnman. Later on the site concentrated on the Pool checkers. Years later the site was reborn as an international checkers library with the support of many volunteers around the world. Now this name is retired, given birth to this, much more powerful, Online Checkers Library.
