How do I edit my profile privacy settings?
All information entered in your profile is optional. If entered, other Sakai users can view your profile information through the Roster tool or through your message posts in the Forums and Chat Room tools. Besides the option to remove the information you have entered in your profile, the display of this information can also be controlled through privacy settings, one for each section of your profile (e.g., Basic Information, Contact Information, etc.).
Note: There is no privacy setting for the profile picture to hide it from other Sakai users. However, users may remove an existing picture which will set it to the default silhouette. Or they can chose an image with which they are comfortable to display to others as their profile picture. See the article, How do I edit my profile photo?
Go to Profile.

Select the Profile tool from the Tool Menu in the Home area.
