If you have multiple CES Administrators and you want to lock down your survey from other CES Administrators, you can do so with the Survey Lock feature.
Overview
Locking a survey will prevent other CES Administrators from being able to view or edit the survey.
Click the Options button to see the Lock options
Lock icons are located in Surveys.
Blue Icons: Indicate these are your surveys and you can lock and unlock them by clicking directly on the icon.
Black Icons: Indicate other CES Administrators have authored the survey and they control the lock on the survey.
NOTE
If the icon is black and unlocked, any CES Administrator CAN view and edit the survey.
