Your design is frickin' awesome! Very cool. With that being said, some thoughts! I'm not too sure about the red rollover you have for the menu, it comes off blured and hard to read. The reason I dont really care as much is because its the rollover image and not the main image, so it doesnt really matter if its read-able or not. If you're a picky designer, I would make the rollover more crisp, if not, whatever! The colors themselves all go together really well.
The forums, again, designed great! Make a link back to the homepage, I didnt find one. Or if you're up the challenge, try and blend in your menu from the index onto that page and keep a similar theme. The forums themselves look great, so no real comments there.
The members list, for now, is short. But in the future, you may want to start making about 4 or 5 columns and putting the members there, coz as the list gets bigger and bigger, the way you have it now, you'll have to scroll a LONG way down to see all the users.
The application form caught me off guard. No design put into it at all! Either open that up in a new window or put some design into it. Your site comes off very professional, so that was a bit of a step back.
The photos, again, you need a link back to the homepage. The rest? Marvelous!
The other pages looked fine. The only other one was the stats page that just didnt look like it came from your site, no design or anything put into it. Also, again, didnt have a link back your page. Try and make that page open in the same page as the index like the links, downloads and matches section.
The one thing I'd say your site is missing is like an about page, what your site offers and what your plans are for the site. Throughout the site, I didnt really find a description of what it is. Obviously a gamer site and anyone who knows gaming will probably pick up on what the site is about. But its always nice to pop a description in. Also, I'm not sure if its just because its in the design stage, but your home link is to C:\\something or the other, so you'll need to adjust that. And make sure you keep consistent with your title tags. Also put in your meta description/content tags. The design is awesome, the scheme is awesome, the quality is awesome. Well done.
