In response to requests, I have created a whatsapp chat only for teachers and educators, called Universitas Magistrorum
Anyone can join, but can only post messages after an interview by an administrator, following which admin status is given. This keeps out bots and non professionals.
THE GENERAL LOCUTORIA ARE:
LOCUTORIUM PRIMUM Junge te! (limited to 257 members)
LOCUTORIUM ALTERUM Junge te! (limited to 257 members)
ΔIAΛOΓOI ATTIKOI ΝΥΝ ΕΣΤΙΝ ΟΜΙΛΟΣ ΤΩΝ ΑΤΤΙΚΙΖΟΝΤΩΝ (limited to 257 members)
NOTE: when you join one of the whatsapp chatrooms, an administrator will contact you to check you are not a software programme, before allowing you to post messages.
