Overrides the <code>wp_notify_moderator</code> function located in pluggable.php. By default, wordpress does not notify a comment author of a moderation 
event. This plugin will look at all users in the blog, and notify anyone who can moderate the plugin, along with the admins and the author 
of that post. This has been tested and does work with WPMU as well.

This plugin allows full control of your user permalinks, allowing you to change both the author base (the ‘/author/’ portion of the author URLs), and the author slug (defaults to the username of the author). You can set the author base globally, or you can set it to be user-specific based on a user’s role. You now have the power to craft the perfect URL structure for you Author pages.
WordPress default structure http://example.com/author/username/.
Edit Author Slug allows for http://example.com/ninja/master-ninja/.
Using a role-based author base would allow for http://example.com/ida/master-splinter/ (for an Administrator Role), or http://example.com/koga/leonardo/ (for a Subscriber Role).
