For selected boards, you can access the advert on the job board directly from AdCourier.
From the manage adverts tab, click on the job title. This will take you to the advert details page. Look to the right of the page. If the job board title is listed in bold under destinations, you can click on the board name to open up the advert.
Alternatively, you can click on the view live advert on [job board name] link in the posting history section, found by scrolling down this page.
If neither of these links are visible for a job board, this means that this functionality is not supported.
