The design on ruk.ca is still being fine-tuned as I wrench the CSS into the modern age. Everything looks almost as it should in Firefox 3. Firefox 2, at least, still has Issues. And the comments pages are a work in progress. Things will return to normal soon. In the meantime, if you miss the sidebar, it’s likely down at the bottom of the page ;-)
Update: things should be back to normal now. Or at least a variation on normal. If the site appears upside down in your browser, please contact me.
