# Internal messaging

From the *Social network* tab (left menu) the *Messages* entry allows you to send or receive messages. It is similar to most messaging tools.

To write a message to another user (or a friend) subscribed to the platform:

* click the *Messages* link below your picture,
* click the *Compose message* icon ![](/files/-MhmvR45f4aJOuzU7TiW),
* Chamilo will auto-complete the send-to field with known contacts,
* enter the subject and message (optionally you can add an attached file),
* click the *Send message* button.

If the recipient has entered their email in their profile, the message will also go automatically go to their email address.

> **Note**: If the other user has chosen to, the message will also be sent to his e-mail as a notification of internal message. However, he will have to enter the platform to answer you.
