We'll create fresh WordPress site with Post Ratings installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Post Ratings is a simple, developer-friendly, straightforward post rating plugin. Relies on post meta to store avg. rating / vote count.
For more information, check out plugin page at dFactory or plugin support forum.
Why another rating plugin? Because the existing ones are either outdated, bloated with useless functionality, or just too buggy 🙂
