Will implement new unread chats based on number of users as a badge on the chat button of all users

Ok! How about notifying the recipient via email for unread chat messages? When prof suggested it, it seemed like his concern was that the vendor won't know that they need to login to the platform to check their messages

Ok i see where prof is coming from. Will try to implement a scheduler function thats checks the chatrooms daily and if there're unread messages (no clicked on), the system will send an email notification of the chat to the vendor

Completed implementation.
