go to the User Home Page (/content-center in the address bar)

click on 'Publish' next to the name of the content item you want to publish; if the action is not 'Publish', then it means the item is not ready for publication

if you want to, edit the content item by going to the 'Authoring' tab, and/or preview the item (see the section called “Previewing the content item”)

go to the 'Lifecycle' tab, enter a Start date/time, and (optionally) an End date/time, then click on 'Publish content item'

If alerts have been installed within your system, add a period of time before the lifecycle will end for an e-mail alert to be sent to remind the author that this needs to be reviewed
