It's a nice, decent clean design. Nothing fancy but nothing wrong with that. I like the color scheme as well.
Nice forum site with a cool and interesting logo but the black color background doesn't seem attractive to me. It's just my personal view.
The design looks good. Just want to suggest to add some text along with your logo. Why not put a title in your site's header? I think this will help to make your site look better and nicer.
The design is not bad but I think there is too much black in the color scheme you should add more colors into the color scheme.
It would be better if the logo can be something different than the current one which you are using. Also maybe you can also consider changing the dark background. It creates that kind of gloomy feeling.
Good logo forum you can improve it by using advertising service and for the discussion board is qutie Good Very interesting Forum
