Watch to see that when a page, folder or site is published Click on the Cascade Button, then Publisher and then Active Jobs.
The Publisher window displays the publishing queue. Each site has it's own publish queue and can publish up to two assets at a time. From here you can see how many people are waiting in line to publish, or if you're behind someone else.
In most cases, Cascade will prevent duplicate publish jobs from being added to the publish queue. If a user attempts to publish an asset that is already in the queue, he/she will be presented with the following warning: This asset has already been queued for publish.
