Hi, I'm planning on using your plugin for Teacher - Family communication in a Kinder, but I don't want families to be able to message other families. I see that in the capabilities addon there is an option to restrict by role, but it doesn't let me restrict messaging between users of the same role. I only want teachers to be able to message families and vice-versa. And the admin being able to message everyone.
Also, is there any way to restrict per user instead of only per role? I'd like to have only certain teachers messaging certain families.
Thank you, love your plugins.
