I've just added code that should make the site readable on iPhones and similar modern small-screen/handheld devices. But I have no reliable way to test it! If you have an iPhone (in particular), PSP, Blackberry, or something like that, I'd appreciate it if you could browse to this site and verify it is readable.
The most obvious difference is the lack of a left-hand margin, but there are other tweaks too. There is one known limitation - complex tables don't crush down onto tiny screens.
