Will the Cloud Bookmark my Content?

Does the Cloud have a bookmark facility?  My course is quite long.  Will the Cloud Bookmark where the user got to and start from
where they left off when they return?

The answer is yes, IF the content is setting a bookmark.  It is the contents job to set the users location.  If it is set, SCORM Cloud will try to get the location and start the user where they left off on re-launch.
