Hello guys, I have been trying to find out how to do it but seems nothing so far, so my question is:
USER A simple user
USER B simple user
USER M power or admin user, or simple user
I want the USER M behing able to see and see and initiate a conversation with USER A and B, and the last two can reply, but i don't want User A and B being able see and initiate a conversation with USER M.
Is this possible to do server side ? or any other way ?
Thanks in advance
