It does seem a bit busy, and my initial thought was "Blrergh" but I guess within a week or so it will be fine, and will think how marvellous it is compared to the old layout.
Give it a week or two to get used to it, it's always strange when a forum changes it's format. Usually most people end up liking the new layout better once they are used to it.
Though don't forget, if you find the colours a bit bright, you can always try the 'cleancut' skin (see the drop down menu in the bottom left hand corner of the forum that shows as default 'CycleChat'.
Look in feedback, and you'll see that two other people at least have raised this. Admin is working on a fix, but is waiting for someone else to write the guff for it...I find it too busy, but I will get used to it.
I prefered being able to scroll over a post title and see what it is about before clicking on it. Can't do that here.
