Troubleshooting: End Users are moving, changing, resizing or deleting assets they shouldn't.

"Position Lock" and "Content Lock" are the controls Admins can use to control content.

Position Lock: Turning this on will lock the position of the text layer for both end users and admins. 

Content Lock: Used to prevent an End User from interacting with the layer.  "Content Lock" removes the layer link from the left-hand menu on the front end.  However, unless Position Lock is also used, the layer can still be moved on the back end, so it is advised that Position Lock is used with Content Lock to prevent the layer from getting moved accidentally during editing.
