It seems there’s a fairly even split after all. I know that the black is sometimes more readable - especially in dark environments the white can seem harsh. I liked it being dark, but when I changed it back after the trial I was happy to see a more open a fresher appearance. The forum is predominantly for reading content, and I think that this look probably serves it better.
Soon I’ll look at Fish-ifying the forum a little more. Although the colours won’t be an option on the site there is a way darker colours can be used. I’ll explain more later when I have a chance 
Thanks for your feedback everyone. Really interesting and useful.
