You need separations. Background colors, table headers, better structure in general. It looks like a bunch of links and stats thrown on a webpage right now.
I think someone already mentioned in another thread that you need to add captions to your login fields at the top so users won't be confused.
Also your second navigation (-Home- -1/16 Armoured Division- -Rc Tanks- -About- -IR Batteling- -Tips + Tricks-) doesn't look like links because the other links in the page are underlined red or at least bold. You should make more obvious.
The logo is big big pain to my eyes below the logo there is some news written, I would suggest you to be professional in language. I have a 1024 x 768 resolution and the website is more than little broad. Navigation Bar is OK, but not good. There should be some separations between Newest Member, Forums Stats and etc.. I would suggest you to remove the Online Members thing. And in the login box, you should label it Username and Password. The color scheme and the design is not so appealing try adding some spice to both of them.
