I link directly to the forum, so I don't actually know what the actual site used to look like. From what I'm getting right now I must say that my one comment would be: "Lacks personality". It all looks a bit - generic.
I also read the "Mission Statement", and the doubles my confusion. The Mission Statement is spot on - but the front page of the site doesn't in any way reflect it. Does it really reflect "fun"? I personally don't think so.
With a base of Mame the options for a nice retro site are almost boundless - instead they seem to have gone with a dull, colorless, flat page that lacks any kind of dynamic pull.
