Non-existent.

Proposed System

How should the perfect solution look like?

A user writes @ and can choose from users in the course.
The user, that is mentioned in a message, is notified.
Tapping a user-mention navigates the user to a one-to-one chat, and creates one if necessary.

A user write # and can choose from channels in the course.
Tapping a channel-mention navigates the user to the channel.

A draft message is saved, when the user leaves a conversation/thread.
The draft is loaded, when the user enters a conversation if present.

A message is queued, if the user is offline.
A job attempts to send the message, when the user goes online.
