Always struck by how badly the website displays on mobile phones - slow to load, scroll around, small tabs at top don't translate well (some like the NGP tab don't register at all). This is a mobile gaming site - how's about optimising it for mobile viewing, surely??
(I use a Samsung Galaxy S modded with Darkyrom, so it ain't me, by the way...! )
Also, the "register" pop out option for the website/forums doesn't work with Chrome - had to enable the IE extension to get it to log in. I'd suggest looking at compatibility with all web browsers as well.
Content is good, but the design generally could do with an overall IMHO folks!
