The one with the coat of arms on black looks quite sharp and classy. But I also don't mind the blue banners ayenee_4.jpg and the WhiteOutNAO.jpg. But really it all depends on what style/colours the actual forum is going to be, to determine what would look best. I certainly tend to go for sharp/classy/clear graphics- but also something that totally stands out from everything else. Something completely... different, loud and proud. I say.
