I find it a little hard to see at a glance which forums have new posts and which don't. Perhaps darkening the color of the 'new posts blue' should solve this problem. It's a minor thing, so it doesn't really have any priority but if you could look into it that'd be great.
(Also I would like to say that otherwise the design is very sleek. Great job!)
