If your eyes are bothered by the white background on the site, go to your profile, go to Preferences, and up at the top is something called "style variations" which is set to "system" by default. On the right of that line is a toggle switch that will pull down a couple of options, and DARK is one of them. You then have to go to the bottom of that long page and SAVE your preference. Then the forum will display with a black background and white text. It is much easier on my old eyes.
