The feedback facility enables people to add feedback to folders and/or topics. That can be an entire book, a specific chapter in the book, or even a specific topic in a chapter. People who browse content can add feedback on the web page and authors can add feedback in their Workbench.
When adding feedback, people can indicate a rate from 1 (not useful) to 5 (useful). Authors can calculated the average rate in their Workbench. In this way they have an idea of the quality of the content.
When someone adds a feedback item, others can add replies to it. One can also add a reply to another reply. In this way a kind of hierarchical feedback tree emerges. Authors can copy parts or all of it and can clean up if necessary.
If the notification facility is switched on, authors can ask for notification the moment someone adds a feedback item to a folder or a topic. Also, the person who adds a feedback item can, in turn, request notification when someone adds a reply to his feedback.
Special permissions in the security settings indicate whether or not people are allowed to add feedback. By default, people also see the feedback added by others. But this too can be changed in the security settings.
