# Introduction
|
|
`GTC` is a command introduced with [MSNP2](../versions/msnp2.md).
|
|
|
|
It is a Notification Server command, without either a request or response payload.
|
|
|
|
It modifies whenever your client handles new users in your Reverse List (RL).
|
|
|
|
# Client/Request
|
|
`GTC TrID [ A | N ]`
|
|
|
|
# Server/Response
|
|
`GTC TrID {list-version} [ A | N ]`
|
|
|
|
Where `list-version` is the new List Version. Removed since [MSNP10](../versions/msnp10.md) in `ABCHMigrated: 1` mode.
|
|
|
|
