Review
The author can send the guide for review and approval by selecting from the list of existing users with review/approval permission.
First, the reviewers receive an email with the review link. After the reviewers watched the guide, they can review it or reject it. In both cases, their review will be signed. If a guide is rejected, the reviewer needs to submit a reason for rejection.
If at least one reviewer rejects the guide, the approval process restarts and everyone needs to review the guide again. Before sending it for review/approval again, the author needs to resolve all the issues.
If the reviewal was successful, the guide status changes from Review/Approve requests/Send for approval with a blue banner (see HERE) to Approve/Approve requests/Send for approval with an orange banner (see HERE).
