The new site layout is sick, however something needs to be done about the banner ad at the top of the site.
Either the ad needs to go, or the photo behind it needs to go. As it stands it looks really un-professional, kinda like something you would have seen on geocities back in '99. I know that the ads are a big revenue earner so its probably going to stay.
In that case the photo background should be removed and something nice done with a gradient background. The new background needs to actually integrate the ad into the header properly, rather than having it look like it's just slapped on top. On the left hand side of the header something needs to be done with the NS logo - this is actually quite important, as currently there is nothing in the header to tell you what site you are on.. common' identity is the most important thing of all!! Most every good site has their logo in a prominent position in the header.
Aside from that, good job guys!
