The layout of scsh.net was designed by Thomas Gärtner. He used the XML library which has been ported from PLT Scheme to scsh to generate the pages.
RT Happe harvested many resources and the posts appearing in the docu section. He's also trying to comfort the various browsers out there with style. (They are not always very appreciative.)
The former webserver of scsh.net is also implemented with scsh: It's the httpd package from the SUnet library.
The webmaster of scsh.net is also implemented with scsh: It's … a bit late, isn't it? Tomorrow we will see clear again, perhaps.
