Tags can be manually applied to each piece of content within the Curate > Manage Content page.
You can apply one or more tags to any individual post or, if you have a number of posts to tag, you can use the batch selection tool and batch apply the tags. You can apply tags to content regardless of whether the post is Disabled, Queued or Published.
Note: You cannot 'create' a new tag directly within the Manage Content page. Learn more about creating new tags here.
