I have searched high and low and cannot figure out how to enable comments (so my reviewers can add their feedback within the course). Help!
Hello and welcome!
First you need to register your reviewers with their email addresses as Reviewers under the “Users” menu.
Then begin a new review, which is done by visiting the Review menu, bottom left of the course screen):
Give your review a title, select your already registered reviewers and choose the options you want, click Create and they will be notified.
HTH!
