How do you know if your items are in Draft status? The quickest way to spot them on the calendar is by the yellow background behind the time displayed.
Before Blog Posts, Social Campaigns, standalone content, or social messages will be published or sent out, the Draft status will need to be changed to Scheduled/Published by clicking on the yellow button in the lower right corner and selecting Scheduled/Published.
Whether is is "Scheduled" or "Published" will depend on the date associated with the item. If it is a future date/time then "Scheduled" will be displayed. If the date/time associated with the item is now or in the past then "Published" will be displayed. (In the example, the date associated with this Social Campaign is Monday, Aug 28th, 2017, which at the time of this writing is in the future.)
