The mail channel on TeamXp sends a message to the web application formatted like an email.
All question types can be used and, if you want the participant to replay, you can use the Open Text question type. This will allow the player to write a reply which will be sent to the facilitator.
This is how it will look in the communicator:
The "cc:" field allows open text replies to be copied to any registered player by entering the corrrect email address. Email addresses for players must already be known otherwise the mail will not be delivered.
More than one email address can be entered in the cc: field separated by commas.
