PublishPress Testimonials
Excellent customer support!

This plugin meets the needs of my project very well. Providing editorial comments for submitted assessments, and a notification system to send emails to both the author and any assigned roles (or individuals) upon content being submitted for approval. This is extended by the easy to use status system, that integrates well into WordPress core, allowing us to create custom statuses and notifications for each. I ran into an issue with notifications not sending to roles and contacted the dev. Their support was amazing! They sent me a working fix for the issue within 12 hours of contacting them!
