DROP allows you to "unregister" a registered group.

Once you DROP a group all of the data associated with it (access lists, metadata, etc) are removed and cannot be restored.

See help on FLAGS for transferring a group to another user.

The FLAGS command allows for the granting/removal of group privileges on a more specific, non-generalized level. It supports registered nicknames as targets.

When only the group argument is given, a listing of permissions granted to users will be displayed.

Permissions:
+f - Enables modification of group access list.
+F - Grants full founder access.
+m - Read memos sent to the group.
+c - Have channel access in channels where the group has sufficient privileges.
+v - Take vhosts offered to the group through HostServ.
+s - Ability to use GroupServ SET commands on the group.
+b - Ban a user from the group. The user will not be able to join the group with the JOIN command and it will not show up in their NickServ INFO or anywhere else. NOTE that setting this flag will NOT automatically remove the users' privileges (if applicable).
+i - Grants the ability to invite users to the group.

INFO displays group information such as registration time, group URL, email address and founder.

INVITE allows you to invite a user to join a "private"/non-open group or a group that is currently full.

JOIN allows you to join a group set as open for anyone to join. No privileges will be set on you when you join a group this way, you will only be listed as a group member.

LIST shows all groups matching a specified pattern.

LISTCHANS shows the channels that a group has access to.

AKICKs are not shown.

REGISTER allows you to register a group so that you can easily manage a number of users and channels.

SET CHANNEL allows you to change or set the official IRC channel of a group. This is shown when a user requests info about the group.

SET DESCRIPTION allows you to change or set the description of a group. This is shown when a user requests info about the group.

SET EMAIL allows you to change or set the email address associated with a group. This is shown to all users in INFO.

SET JOINFLAGS allows a group to specify the flags assigned to a user when they JOIN the group (if the group is open).

Note that this must be valid, else "+" will be set on joining users. If no parameter is provided or the parameter is OFF, the join flags will be returned to network default.

See "/msg GroupServ HELP FLAGS" for details of the different flags that are valid here.

SET OPEN allows a group to be open to any user joining whenever they like. Users that JOIN the group will have no privileges by default.

SET PUBLIC shows group membership when users request NickServ INFO of members of the group.

SET URL allows you to change or set the URL associated with a group. This is shown to all users in INFO.
