Permalinks for quote authors

Create a custom taxonomy quoteauthor, activate pretty permalinks, and you get nice URIs automatically. These URIs will not put the author’s name right behind the root, but something like /qa/steve-stevenson/ should be good enough.

Here is a sample code as a plugin, you can download it on GitHub
