Only show what pertains to a person or their students on the recent activity feed. If a parent doesn't have a high school student, they shouldn't see anything posted to high school. It clutters their feed with unnecessary things and they can't rely on it to quickly find inforamtion they need.

It could be helpful for students to be able to NOT show courses in which they are still technically enrolled even though the class is over, so that they could look back on content in the class without needing to be dropped from the class.
