Thanks for sharing your site. I really like the theme, it's nice and clear and efficient looking. Obviously now you need to focus on getting some more members. It's also not initially apparent what the purpose of the site is. General discussion, specifics?
Why do you use teenbb.tk/web/ as the initial url of your site? It's probably better to get rid of the web part.
I agree with stpvoice that the purpose of the forum has to be made clear. Visitors have to find a reason in order to become a member of this site.
