I'm looking for a plugin which allows me to modify the default behavior of the page slugs.
For instance, by default a page with "My Page Title" gets a page slug of "my-page-title". I need the *default* page slug to be "my_page_title" instead.
Is there a plugin or way I can make this happen? Is it possible for me to write my own plugin, hooking into the slug-generation routine and making that happen?
