TECHNOLOGY- Messaging site WhatsApp is likely to give more power to group administrators in future. One of them being to restrict all other members from sending text messages, photographs, videos, GIFs, documents or voice messages.
According to WABetaInfo, a fan site, WhatsApp has submitted the "Restricted Groups" setting via Google Play Beta Programme in the version 2.17.430.
The feature will allow members to only read messages but they would not be able to respond. The members would need to send a message to admin for approval and only then the rest of the group will get it.
