This plugin gives you full control over the permalinks for author pages. When using “pretty permalinks”, by default URLs to author pages are structured:
http://www.example.com/author/author-name/
With this plugin you can change the “author” part of these URLs into anything you like, for example:
http://www.example.com/editorial/author-name/ 
http://www.example.com/crew/author-name/ 
http://www.example.com/members/author-name/ 
http://www.example.com/posts-by/author-name/
The plugin will also automatically change links throughout your site that point to author pages. The URLs of author feeds are also changed.

In WordPress 2.9 custom post type was introduced, that opened a new world for many WordPress developers. 
When it comes to removing the slug and not destroying the rewrite rules for other post types this plugin works great. 
This only concerns those who are using %postname% as permalink structure and want to add a custom post type so that 
the urls for them are in the same way as normal posts and pages: http://siteurl/%custom_post_type_title%/.
