Several days ago, the light style/theme sporadically stopped working around the forum if one isn't logged in.
Some subforums apply it, some do not; I haven't checked all of them (I can make a list, if that helps you), but for example, the front page is dark, while this Help & Feedback subforum is light.
It's not a huge deal, but if you're mostly a lurker, or an outside visitor, and you're one of those people who get eye strain and afterimages from dark themes (astigmatism, I believe), then using the forum with its dark theme might be a bit problematic.
