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

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

Renames a user. For the commands that replaced REA with a `MFN` property, read [PRP](prp.md) and SBP.

# Client/Request
`REA TrID user-handle new-friendly-name`

Where `user-handle` is the user handle that you'd like to change the friendly name of.
If this is the current user's handle, the change will be announced via
[NLN](nln.md) to all users on your Reverse List (RL) if they are not in your Block List (BL).

Where `new-friendly-name` is the friendly name you'd like to set.
Subject to server-side restrictions.

# Server/Response
`REA TrID list-version user-handle new-friendly-name`

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