For compatibility reasons this site does not contain frames or applets. The few lines of JavaScript embedded in our pages are used only for data validation of entry fields and are transparents to non JavaScript enabled browsers.
One of our goals, designing this site, was to make it simple and fast to download. We hope to have come close to this goal.
One important part of this site experience is of course on-screen colors. Please check our display setting page for more information about system color configuration.
