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

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

Creates a new group.
Replaced with [Address Book Service](../services/abservice.md)'s
[`ABGroupAdd`](../services/abservice/abgroupadd.md) in [MSNP13](../versions/msnp13.md).

# Client/Request
`ADG TrID group-name {0}`

Where `group-name` is the name of the group you'd like to create.
Has a limit of 61 bytes (URL encoded characters count as 3 bytes).

Where `0` is always `0`. Removed in [MSNP10](../versions/msnp10.md).

# Server/Response
`ADG TrID {list-version} group-name group-id {0}`

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

Where `group-id` is your new group's identification number.

Where `0` is always `0`. Removed in [MSNP10](../versions/msnp10.md).
