Meaning no offense to Jin, the current SFF theme is murder on my eyes (my eyes are probably more at fault than the designer :)
I'm rather weak at CSS-fu, especially on the user side (e.g. fixing CSS in the browser for sites I don't control).
What would be a good SE site to ask this question on? (e.g. "How can I remove the SFF specific design and replace it with StackOverflow standard design?)
