LearnDash Private Message Conversation Types

In the LearnDash Private Messaging plugin there are multiple conversations types which are:

• Private chat between only the teacher and the student — This prevents conversations between students but does allow a teacher to message a student or a student to message a teacher (admin).
• Private chat within a group — Allows student to student and student to teacher communication (note group support is enabled by default).
• Only admins can send messages.
