User Mode +g Documentation
+Support of this specification is indicated by the CALLERID token in
+RPL_ISUPPORT (005). This token takes an optional parameter, of the letter
+of the user mode. If no parameter is specified, the user mode is g. A
+typical token would be: CALLERID=g
+The rest of this specification will assume the user mode is g, as
+implemented in hybrid, ratbox and charybdis.
+
Hybrid 7 includes a new and power feature that all users can take advantage
of to help prevent flooding and unwanted messages. This new feature is
invoked by setting user mode +g. When a client is set +g, that user will
The target of the message will only receive one notification per minute, from
any client, in order to help prevent flooding. The sender will NOT have the
-rate limit, and will receive a notice saying the target is in +g mode every
+rate limit, and will receive a numeric saying the target is in +g mode every
time they send a message. Note that this behavior is similar to the way AWAY
messages are done.
Removing a user from your accept list is also simple. Issue the command
ACCEPT -<nick>.
+The ACCEPT command can be used whether or not +g is enabled at the time.
+Setting -g does not clear the accept list.
+
+Some users (in particular IRC operators and services) may be exempt from
+CallerID, and able to message a +g user without being on their accept list.
+
+Being on the accept list may allow a user to bypass more than +g (for example,
+a +R user can use the ACCEPT command to receive messages from unidentified
+users in charybdis).

Sample Session
The easiest way to see how this works is by experiencing it. Seeing a sample

Client Hwy101: /msg Hwy-LL hi
-Hwy101 will see: -Hwy-LL- *** I'm in +g mode (server side ignore).
- -Hwy-LL- *** I've been informed you messaged me.
-
-Hwy-LL will see: Client Hwy101 [wcampbel@admin.irc.monkie.org] is messaging
- you and you are +g
+Hwy101 will see: -!- Hwy-LL is in +g mode (server-side ignore.)
+ -!- Hwy-LL has been informed that you messaged them.
-The sender will receive the NOTICE from the target of the message, while
-the recipient will receive the NOTICE from the server.
+Hwy-LL will see: -!- Hwy101 wcampbel@admin.irc.monkie.org is messaging you, and you have umode +g.
--
If Hwy101 sends another message to Hwy-LL (before the minute expires), he will
-see: -Hwy-LL- *** I'm in +g mode (server side ignore).
+see: -!- Hwy-LL is in +g mode (server-side ignore.)
and will not receive the second notice
-Hwy-LL will NOT see any notice.
+Hwy-LL will NOT see any notice. This also applies if the second message comes
+from a different user.

We hope that these goals are obtained.
+Numeric replies
+---------------
+
+280 - RPL_ACCEPTLIST
+--------------------
+:<server> 280 <nick> <accepted1> <accepted2> ...
+
+This numeric is used to indicate to a client the list of nicknames they are
+accepting. At most 15 accepted nicknames may be included; if this is exceeded
+multiple RPL_ACCEPTLIST must be sent.
+
+281 - RPL_ENDOFACCEPT
+---------------------
+:<server> 281 <nick> :End of /ACCEPT list.
+
+This numeric is used to indicate to a client the end of an accept list.
+
+456 - ERR_ACCEPTFULL
+--------------------
+:<server> 456 <nick> :Accept list is full
+
+This numeric is used to indicate to a client that their accept list is full
+and one or more nicks could not be added.
+
+457 - ERR_ACCEPTEXIST
+---------------------
+:<server> 457 <nick> <target> :is already on your accept list
+
+This numeric is used to indicate to a client that the given nick was already
+on their accept list.
+
+458 - ERR_ACCEPTNOT
+-------------------
+:<server> 458 <nick> <target> :is not on your accept list
+
+This numeric is used to indicate to a client that the given nick was not on
+their accept list.
+
+716 - ERR_TARGUMODEG
+--------------------
+:<server> 716 <nick> <target> :is in +g mode (server-side ignore.)
+
+This numeric is used to indicate that a message (PRIVMSG) the client sent
+could not be delivered because of CallerID restrictions. The <target>
+parameter is the target user's nick.
+
+717 - RPL_TARGNOTIFY
+--------------------
+:<server> 717 <nick> <target> :has been informed that you messaged them.
+
+This numeric is sent after 716 if the target user was notified of the message.
+
+718 - RPL_UMODEGMSG
+-------------------
+:<server> 718 <nick> <target> <user>@<host> :is messaging you, and you have umode +g.
+
+This numeric is sent when a message (PRIVMSG or NOTICE) sent to the user is
+blocked by CallerID, at most once per minute.
+
+Problem: hybrid uses the following form instead
+:<server> 718 <nick> <target>[<user>@<host>] :is messaging you, and you have umode +g.
+which is ambiguous if the user may contain a [ and in the author's opinion ugly.
