Managing permissions in TaskReviewer is easy through our web app (we will be bringing these controls into the extension soon!).
You can easily modify these permissions my going to My Account from the Browser extension, then clicking on the Team Tab on the left side of the screen (Admins and Account Owners only by default).
Create Review Permissions
By default all users (paid users) in your Teamwork account will have access to the review tool. This allows them to create reviews if you wish you can remove this permission by toggling the Create review option next to their name .
