Notes:
Content - What you're seeing now is being written in the content page. What ever you want shown when they visit http://havisham.net you type here.
CSS - Copy everything in here when making a new page. The CSS will basically customize the site with fonts and such. There's a way to make it so that you don't have to copy it onto every page but it doesn't work for Mozilla so copying everything is a must.
When uploading everything onto the net the background picture might not work. If it doesn't you may have to edit the name of the layout. If you upload it as layout.jpg and it wont work rename the file as .JPG and it'll work.
