We are looking for a solution to utilize the immensely powerful tools of the workshop activity and peer evaluation in a large user course that is self-paced.  

It does not work to close off the submission phase and start the assessment phase all at once. Need this to be a fluid process.  Learners are still able to submit assignments, but also able to assess assignments.   

Has anyone ever found a way to make this work or a plugin that can be used to add this functionality?

Thanks!
