Re-arrangement of login box and navigation

[John]

You will probably have noticed that the login box is now beside the logo at the top of the forum rather than beside the Navigation guide (the thing that tells you where you are in the forum). The first google ad has also jumped down below the navigation. I'm trying to compact the top part of the forum. Also, at the top of each forum thread or post you will probably notice summaries - this is to help the site's rankings on things like google.
