CCLE Feedback activity

The members of my collaboration site want to issue a survey to UCLA members who are not part of the collab site. How can we do this? 
 Using the Feedback activity, you can make it “public” following these steps: 
 1) In the course settings, set Guest access – Yes 
 2) Create the feedback activity. 
 3) In its settings set it to Group mode – No groups and Grouping – None 
 4) In Permissions, go to Advanced role override – Authenticated user 
 5) Set mod/feedback:view and mod/feedback:complete to allow for Authenticated user
