The main genius site with more info on what is genius: http://www.jirka.org/genius.html
This is a site for sharing snippets of code, ideas, etc... and other random useful bits of information about genius. If you want access I guess you have to email me (jiri.lebl at gmail dot com) and I can add you to the collaborators or whatnot. It seems Google sites doesn't allow possibility of just anyone editing pages.
