The idea and concept of this plugin is great.
- The plugin will create a page 'All Authors Page' which isn't mentioned in the instructions.
- The plugin uses the Gravtar image. If you have a custom avatar setting, the the plugin won't show it.
- The plugin is bare-bone. You need to write your own CSS.
So, overall a nice idea, but unfortunately at this stage the plugin creates more work than just creating an author page by yourself.
