Ian Lloyd over at Accessify.com just made creating CSS-based navigation lists incredibly simple.
List-o-matic (not to be confused with it's excellent inspiration, Listamatic) is a wizard for quickly creating unordered navigation lists, while allowing you to choose from a few different CSS styles, such as my Mini-Tabs and others.
Enter a few link names and URLs, choose a style and ... bingo. You have yourself some styled navigation. It doesn't get any easier than this.
Oh, and YARRR!
