Thanks Raydar but that wont quite work. It may be the same forum software but it's certainly not the same style. CSS from another site is not something that can be plugged in and expect to work. We're in the process of a redesign at the moment. I'll be adding a red theme, it's no big deal.
But as someone already mentioned, a "red theme" is not red light as such, so the effect is not as good as actually using a red filter over the screen. A red theme is merely darker - better than white but not red, night vision friendly light.
But if you guys want red, you guys can have red. No worries
