This site was developed and most extensively tested with modern browsers supporting current web standards. It is designed to work acceptably with older browsers, but some cosmetic features may not display properly. If this interferes with your enjoyment of the site, we urge you to upgrade.

The Unicode system is used extensively on this site to display Greek and other non-Latin characters. Modern desktop operating systems tend to have good application and font support for Unicode; older systems may have incomplete or non-existent support.

Similarly, this site was designed and most extensively tested with up-to-date displays, most with at least 1024 by 768 resolution and thousands of colors ("16-bit" or "High" color). With configurations lower than this level, cosmetic display problems may occur, but should not interfere with the function of the site.

Another feature in modern desktop operating systems that may enhance your use of this and all web sites is font smoothing. This technique blurs the edges of text characters on your screen to make your display look more like a printed page. Windows XP and Mac OS X have the best support for font smoothing; other operating systems and older versions of Windows and the Mac OS have weak or non-existent support for it.

The following screens captures, from the same browser, show the difference enabling font smoothing can make:
