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

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

Adds a user to a list. Replaced by [ADC](adc.md) in [MSNP10](../versions/msnp10.md).

# Client/Request
`ADD TrID [ FL | AL | BL ] user-handle custom-friendly-name {group}`

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

Where `custom-friendly-name` is the friendly name of this user you'd like to store in this list.

Where `group` is the group to add the user to.
Only applies for Forward List (FL). Since [MSNP7](../versions/msnp7.md).

# Server/Response
`ADD TrID [ FL | AL | BL | RL ] list-version user-handle custom-friendly-name {group}`

If this is an asynchronous use of this command, the Transaction ID (or `TrID`) will be set to `0`.

Where `list-version` is the new List Version.
