Jigsaw Puzzle - changes to the site layout

I've made quite a number of changes to the layout and features of the site overnight which I hope are an improvement & haven't made it too busy. In particular, I've gone back and labelled properly all the old posts so you can now browse by person or topic or place. I've also installed a custom search engine at the top which is slightly biassed towards archaeology, pottery and food. To clear the search results, use the back button in your browser. Also if you're interested and want to be kept up to date with new posts, you can now subscribe either via a reader or by email.
