WhatsApp's answer to Discord may be group chat 'communities'
 

WhatsApp group chats may soon behave more like Discord servers. WABetaInfo and The Verge have learned WhatsApp is developing a Communities feature (initially spotted at XDA) that lets administrators unite group chats under a larger umbrella. You'd have a top-level Community chat with smaller group chats tied to it — for instance, you could have a Community for a college course with study group chats linked to that parent.
