Update this site using the new version of K2 0.9.1. The developers have done an excellent job, especially on the backend. No more sidebar blues, because you can now totally customize the sidebar with modules, that you can drag and drop, insert custom php code (like the tagcloud on the right) and html (like the technorati link and feedburner rss icon).
Also added a new K2 style named Sawchuck. Named after a fearless hockey goalie.
