I didn't want to write this initially (and I'm still not sure if it's the right board), but the issue ramains the same for me.
I don't know about anyone else's experience, but the move from light background/dark text to dark background/light text on this Wiki was really heavy for my eyes. I thought they might adjust with time, but the contrast between Wiki and almost every other major websites that I (and many others, I'm sure) use frequently - Goggle, YouTube, Wikipedia, Twitter, other social networks and so on - remains. When I switch them to this Wiki, it's genuinely hurts my eyes!
So I'm not sure what to do. It's not comfortable at all for me to read or edit here with this dark background, and after long exposure to darkness it's even more painful to adjust back again to the light ones (which, again, is every other that I use, apart from this Wiki).
