Well, the problem isn't the black on white text. That part is fine, my issue is that the forums background is pure white as well. When you got a wide screen like I do, it ends up in a lot of white. That stresses my eyes way too much, especially in the evening/at night.
As is now, I have to minimize my browser to cut off all the extra background, unless I want a headache in the long run :C

Just tried to edit the background on a screenshot to #ddd and that would be a great improvement! Definitely enough for me to avoid headaches.
