The node to node messaging (`node_msg`) module allows users to send messages to one or more users on different nodes. Messages delivered to nodes follow standard [User Interruption](../misc/user-interrupt.md) rules.
*`dateTimeFormat`: [moment.js](https://momentjs.com) style format. Defaults to current theme → system `short` format.
*`messageFormat`: Format string for sent messages. Defaults to `Message from {fromUserName} on node {fromNodeId}:\r\n{message}`. The following format object members are available:
*`fromUserName`: Username who sent the message.
*`fromRealName`: Real name of user who sent the message.
*`fromNodeId`: Node ID where the message was sent from.
*`message`: User entered message. May contain pipe color codes.
*`timestamp`: A timestamp formatted using `dateTimeFormat` above.
*`art`: Block containing:
*`header`: Art spec for header to display with message.
*`footer`: Art spec for footer to display with message.
## Theming
### MCI Codes
1. Node selection. Must be a View that allows lists such as `SpinnerMenuView` (`%SM1`), `HorizontalMenuView` (`%HM1`), etc.
2. Message entry (`%ET2`).

*`userId`: User ID.
*`action`: User's action.
*`userName`: Username.
*`realName`: Real name.
*`location`: User's location.
