Not too much to evaluate here, I think.
The content is almost absent and the design looks like oh-another-forum-default-skin.
You should do something to make your website differentiate from other forums, if you want to succeed.
Just take a look at some websites you find successful, study them for a couple of minutes and you'll realize that people use them because they have something that makes it different from the others. Even if they look like crap, their content surely is strong.
After all, content is king.
