You can send private messages to other users using the Messages function. The recipients can be specific users or users involved to specific courses, groups or branches depending on your user type.
The administrator can communicate with every group and branch of the system, while a simple user can communicate only with users that share common groups, branches, courses etc. This behavior is controllable from the user-types (available only to admins).
The Messages section displays your Incoming messages along with their status, as well as a second tab (“Sent”) with a list of messages you have sent.
