Font rendering in Chrome
Some of the fonts you use are rendering rather badly in Chrome when compared with IE9 on Windows 7. The worst offender is the font used for the forum posts. It looks very jaggy in Chrome whereas in IE9 it is nicely anti-aliased. Firefox is the same as Chrome. I've not tried Safari yet or any browsers in OS X. I know rendering is the bane of web design but I would expect your target audience to be Chrome users so it would be good for the fonts to be better.
