Skidoo Too : Ruthsarian Layouts is a rather simple 3-column layout with a flexible middle column. The special feature: the order of the source is such that the middle column comes first. This improves usability for Lynx users because they can immediately access the content and do not have to skip the navigation first. The layout is Public Domain.
He also has another layout on the page that has two flexible columns and only specifies the left column as fixed, same source order.
