# Messages As the administrator, you can send messages to JMap users from JMap Admin. The messages will be displayed in the user interface (JMap Pro applications only). Users who already have an active session will see the messages immediately. The other users will see the message the next time they log on. Messages can be used to inform users of service interruptions, for example. Messages will be displayed each time a user starts a new session, during the validity period of the message. ## Sending messages To create a new message to be sent to all users, press **Create** from the **Messaging** section.


New message to users
Subject	A short text describing the subject of the message.

Valid from	The date and time from which the message will start to be displayed.
Valid until	The end date and time from which the message will no longer be displayed. After this date and time, the message will disappear from the list.
