+# Introduction
+`ADC` is a command introduced with [MSNP10](../versions/msnp10.md).
+
+It is a Notification Server command, without a request or response payload.
+
+Adds a user to a list.
+For the command that was replaced with this, read [ADD](add.md).
+For the command that replaced this command in [MSNP13](../versions/msnp13.md), read ADL.
+For the service that complements ADL, read about the [Address Book Service](../services/abservice.md).
+
+# Client/Request
+
+## Add to a list
+`ADC TrID [ FL | AL | BL | RL ] N=user-handle {F=stored-friendly-name}`
+
+Where `user-handle` is the target's user handle.
+
+Where `stored-friendly-name` is the friendly name you'd like to store.
+Only applies if the target list is the Forward List. It and the `F=` prefix are omitted otherwise.
+
+## Add to a group
+`ADC TrID FL C=contact-id group-id`
+
+Where `contact-id` is the contact's ID associated with the user on your Forward List (FL).
+If in `ABCHMigrated: 0`, this is the contact's user handle,
+otherwise in `ABCHMigrated: 1`, it is the contact's GUID.
+
+Where `group-id` is the identification number of the group you'd like to add the contact to.
+If in `ABCHMigrated: 0`, this is the group's numeric ID,
+otherwise in `ABCHMigrated: 1`, it is the group's GUID.
+
+
+# Server/Response
+
+## Successfully added to list
+`ADC TrID [ FL | AL | BL | RL ] N=user-handle {F=stored-friendly-name} {C=contact-id}`
+
+Where `contact-id` is the contact's ID associated with the user.
+Only applies to users added to the Forward List.
+If in `ABCHMigrated: 0`, this is the contact's user handle,
+otherwise in `ABCHMigrated: 1`, it is the contact's GUID.

+
+# Client/Request
+```
+SDC TrID target-address translation-lcid requesting-library client-identification X X my-friendly-name length

+````
+
+Where `target-address` is the E-mail address or index from the last [FND](fnd.md) response you'd like to invite to the service.
+
+Where `translation-lcid` is the LCID of the translation you'd like the invitation to be in.
+
+Where `requesting-library` is the name of the library that requested this CVR, usually `MSMSGS` or `MSNMSGR`.
+
+Where `client-identification` is the internal name of the codebase used to create `requesting-library`, usually `MSMSGS`.
+
+Where both `X` parameters are always `X`.
+
+Where `my-friendly-name` is your current friendly name.
+Invalid escaped characters are forcefully re-encoded to`%3DXX`,
+where `XX` is original escaped character code
+
+Where `length` is the length of the payload.
+Set to `0` if you don't want to add anything else to your invitation.
+
+Where `payload` is plain-text data that is included in the invitation.
+If this is `0`, this parameter is empty.
