UserVoice is a Customer Feedback system that makes it easy for your users to report bugs and vote on new features. From the UserVoice website:
“UserVoice allows your customers to vote on feedback and ideas submitted in the customer community. There is a limit on the number of votes a user can spend at any given time. When a customer creates an account, they are given 10 votes they can use as they see fit.”
The UserVoice WordPress plugin makes it easy to integrate the UserVoice customer feedback system with WordPress posts and pages without having to directly edit WordPress template files.
