I've implemented that now. I should release the version during the week-end. In the new version (May 2009), you'll benefit from the following new features :
- Blog comments are supported
- A "Show Ratings" webpart is now available to show the webpart of the current site or site collection. Ratings are grouped by value (5 stars, 4 stars etc...) and visitors can rate and view existing comments from that webpart.
- A new application feature is delivered to copy the language files in the App_GlobalResources of the targetted webapp
- A new site collection report is accessible from the site collection settings
- The application pages have been relooked to mimic the look & feel of the standard UI
- New stsadm commands (extensions) have been added to facilitate the installation of the rating system and also to provide rating reports directly from the console
I'll update the manual during the week-end.
