As requested, I've decided to go ahead and make us our very own DARK theme for the forum. This theme will work in Chrome and Firefox, you'll need to have Stylus installed. When prompted, copy the code here:
You'll get all of the work I've put in, a bit of a stop-gap solution but it should work for the moment. There are a few little things I couldn't get stylus to replace, but for the most part the vast majority of the forum has the dark theme applied. Enjoy!
