Currently this SMF forum just goes along with it's default theme (my previous try got burned up in spam, needed some hasty action).
Later like for the main RRPGE site and my blog, I plan to design some dark theme preferably myself. Of course given that the forum is theme-able, I will retain the possibility for selecting a bright theme for those who like that. Why I like the "dark side" is that my eyes are quite sensitive: I can not much endure the usual bright background designs for long. Dark also gives some good retro-ish feel which is a nice thing to have here.
