At the moment, every user can set a Comments block on their profile and allow others to comment. This is independent of course enrolments.
I can see how many organisations, namely schools, would like to have the capability to turn this off/on. Just imagine kids spending chatting away on Comments pages and frustrated teachers monitoring & asking to stop the distractions ... For the record, I'm against such bans but the realities sometimes do call for OFF button.
Could we give Admin or Manager the ability to disable Comments block just on profile page sitewide, but keep it in courses where the block could indeed be very useful.
