# Introduction
`FLN` is a command introduced with [MSNP2](../versions/msnp2.md).

It is a Notification Server command, without either a request or response payload.

It specifies that another user in your contact list has gone offline.

# Client/Request
This command can not be sent from the client.

# Server/Response
`FLN {user-handle} {network-id}`

Where `user-handle` is the related user's handle.

Where `network-id` is the Network Identification Number that this user is from.
Added since [MSNP14](../versions/msnp14.md).
