What is a "discussion" in EDT?

The tab Communication > Discussions works like a classic e-mail, organized into threads: when you start a discussion, replies are added in a tree-like fashion. For this reason, it is advisable to limit the number of recipients to a strict minimum (especially if the discussion is aimed at students or guardians) or to use another communication tool (information, for example). 

With a Client EDT connected to an EDT base, you can initiate a discussion with other Client EDT users. With a Client EDT connected to a PRONOTE base, you can initiate a discussion with everyone in the school - including students, guardians and teaching assistants.
