Thanks for all the feedback, good to hear that it seems to have gone smoothly.
Anyone getting yellow/orange dismiss any notice you might have when you first come on the sit, although there should be none today. If there is dismiss it and refresh.
Some might have been caught on the mobi style, you can change this at the top, I think it says 'Full Site' or some such, generally the skin can be changed down on the bottom left corner, although at the moment there's little choice.
