Hi @arovner,

Would you like to prevent students in a class from messaging each other, as the original poster of this thread was, or would you like to do something different?

Disabling students from messaging each other would be in your account -> permissions area on the course roles tab.  The relevant rows there would be "Conversations - send messages to individual course members" and "Conversations - send messages to entire class."

If you'd like something other than this, please describe your goal(s) and community members here can try to offer some suggestions.

Hope this helps!
