We also would like more control over this. We have no problem if students/parents want to hide certain contact information from other students or from other parents, but we do not want them to have the ability to hide important contact card information from teachers and non-teaching staff. Teachers access their roster and use the "view relationships" link to see parent emails and phone numbers in order to contact parents about academic or behavior issues, but a number of students have "hidden" their relationships from teachers so that they cannot contact parents easily. As a Platform Manager, I can enable this again, but nothing prevents the students from hiding it once again.

Yes, need to prevent students from making changes.

I'd actually like to block students from making any changes to the "Select information to be published in the online community." option. Parents, alums, adults - sure - but student info is almost always typically set by the school and having students mess with it causes lots of issues.

Each year we have one or two Middle School students who figure out how to edit these settings - and they remove themselves from view - causing the parents to call in a panic.  "What happened to my child?"

Yes, please.
