Absolutely archaic system with no support from customer service, if you can even find the contact form. Once you do, they won't be happy. When you're grading your peer's assignments the grades don't show so people start to think you haven't reviewed them. The system repeats comments you've made; it keeps deleted comments up and attributes empty streams to you. It's almost impossible to contact customer service about these issues. When I finally got hold of customer service to ask them to take the repeated and incorrectly attributed posts down, they kept chopping and changing who was dealing with me. They asked me to send screenshots and then refused to read them and then bizarrely told me they don't grade assignments. Coursera's customer service team is unprofessional and goes out of their way to be unhelpful.
