With the help of ainwood I've created a Dark CFC Forum Style. To select the style, you can go down to the footer on this page and click on the words "Civilization VI" or "Modern CFC" (depending on which style you're currently using), located next to the language option. You will be given a set of options, one of which is "Dark CFC (WIP)". Alternatively, you can change the style in your profile preferences. The style is currently a work in progress, so feedback on how it could be improved would be appreciated. If there are individual elements that you think are hard to see, or that could be better, then please post here and I'll see what I can do. There are several hundred individual settings that go into a forum style, so there's bound to be some choices that don't quite work, or that conflict. I also never used the old Black vBulletin theme, so I'm not 100% sure what those wishing for a dark theme are after. I would also be able to work on further forum styles, by popular demand.
