# Introduction
`RMG` is a command introduced with [MSNP7](../versions/msnp7.md).

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

Removes all users from a group and the group itself.
Replaced with [Address Book Service](../services/abservice.md)'s
[`ABGroupDelete`](../services/abservice/abgroupdelete.md) in [MSNP13](../versions/msnp13.md).

# Client/Request
`RMG TrID group-id`

Where `group-id` is the identification number of the group you would like to remove.
With `ABCHMigrated: 1`, this parameter is instead the GUID of the group you'd like to remove.
You cannot remove the "Other Contacts" group (group ID `0`).

*NOTE: If users are exclusively in the group you remove,
THEY WILL BE ALSO REMOVED FROM THE FORWARD LIST (FL).*

# Server/Response
`RMG TrID {list-version} group-id`

Where `list-version` is the new List Version. Removed in [MSNP10](../versions/msnp10.md).

# Examples

## With List Versions
*Only in [MSNP7](../versions/msnp7.md) to [MSNP9](../versions/msnp9.md).*
