Received message from server
Received message from bob: Hola a todos

Note: The message was received correctly, but there is no garantee that it will reach any of the rest of the registered clients. The server sends the messages and does not wait for a response from the clients.

WARNING: Users need to be logged in before being able to send messages. In order to log in, the user needs to be registered first. Users need to use the same retransmission server in order to be able to communicate.
