We'll create fresh WordPress site with WP Default Author installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin allows blog admins to change the default author globally so that when any user posts it appears under the same name.
Admins and editors can also change the default author for a single user. This setting takes precedence over the global setting.
The plugin is available at github: http://www.github.com/birgire/wp-default-author
