A pattern editor (also known as a tech editor) can access your patterns, even draft/unpublish ones, directly from your shop. Much like you, an editor can open your patterns in Ribbuild mode and edit them. Editors can only be set for all your patterns. To set an editor head over to your Shop manager and click the testing tab. Choose the editor role and enter the username of the editor. Finally, click the 'Add' button. We highly recommend you add only trusted people as editors.
