EIC is able to add a language editor/additional AE for manuscripts in "Waiting for EIC" status if AE/Reviewer's comments are not satisfactory enough. In order to do that, EIC should choose the correct role from the top-right corner of the website and enter "WAITING FOR EIC" status. At this step there is button for "Add Language Editor" and a list of associate editors will be shown.
Afterwards, the language editor should see the article on his/her panel in "New Invitation" and do and submit the review by clicking on "Submit Language Editor Comments" button.
