Unlike the news feed viewed by all the members of the class, the chat is private. The teacher can start a private chat with a parent, or a group of parents when he/she wishes to. The teacher can also decide whether or not the members can chat with him/her.
To activate or deactivate the chat between members, click on the little arrow next to your class then select “modify your class”. You simply have to check or uncheck the box “authorize the chat between members” and then click on “save” to save your changes.
When the teacher sends a private message to a parent, he/she has the possibility to logout by clicking on the arrow next to the chat box then on “logout”. The parent will not be able to send him/her messages. The teacher is the only one who can relogin. The teacher is the master on board !
