More Forum Styles

Create a custom style yourself (it's primarily just a stylesheet switch) and submit/post it for consideration, there's various browser plugins you can use to help you do this (Stylus to name one). If you want to write a style and post it, i'm sure the team would be open to the idea of making into a selectable style. I don't speak for them, but i can't see the harm and you can always use it personally regardless (i write styles for sites i use).
