Unlike most sites on the web which tell you nothing about everything here I tell you everything about nothing.
Warning: These pages are under permanent construction and are never to be finished. They can be moved to another server without previous warning as happened to them many many times. As logo says I started them in 1996. That time I hosted them on my personal server then moved them to Geocities, then to Netscape and so on. Eventually they can be neglected as happened to them for last couple of years as I was not in the mood to keep them updated. Eventually they may be deleted completely if I become mad or come to conclusion it is wise to do so or both.
