If your work needs to be authorised by another user before publication you must submit it.
When you have submitted a page to the next step in the workflow, it will sit awaiting approval until it is authorised.
You will not be able to edit this original page, but you will be able to open it up as a Read Only copy.
You can however, revoke a submission at any time before it is authorised.
To submit work for authorisation:
Click on the Workflow drop down arrow
The Submit & Authorise option will only be available if you have authorising permissions set up.
Select Submit from the drop down menu
The Authorisers/s will then receive an email notifying them that the page is awaiting their approval.
