MetOpen- open source news, reviews and addons has released a new PHPNuke addon: MetAuthors. This allows you to quickly see all your readership stats so you can determine which types of content and which authors work best on your site.

MetAuthors projectpage :: MetAuthors Demo-Page

Features: When an author logs in they will see their listings highlighted. Admins can easily reassign an article to the proper author. (This is useful when the nuke admin posts a story that is received by another.)
