 +[[dcc]] chat <​nick>​ [-p <​port>​]
 +[[DCC]] CHAT offers to another user, or accepts an offer from another user,
 +for a direct connection between your clients. ​ This direct connection allows
 +you to talk to that person without the messages passing through any irc 
 +network.  ​
 +Because the messages are not sent over irc, they are both less prone to
 +snooping by others on irc, and they are delivered faster and have 
 +guaranteed delivery (which irc does not guarantee because of netsplits).
 +Because the messages are not sent over irc, it requires that the other 
 +peer know your IP address. ​ This may be undesirable if your hostname is
 +spoofed on the network. ​ Do not offer (or accept) dcc connections with
 +those who you do not want to know your ip address.
 +To send a message across a [[DCC]] CHAT connection, use the [[MSG]]
 +command as you normally would, but prefix the other person'​s <​nick>​ with
 +an equals-sign ('​='​). ​ The <​nick>​ is the one that you gave to the
 +original [[DCC]] CHAT command. ​ Even if they change their nickname on
 +irc, you must still refer to them by the nickname you gave to [[DCC]] CHAT.
 +You can change the <​nick>​ with [[DCC]] [[DCC RENAME|RENAME]].
 +You can send a [[CTCP]] command across a [[DCC]] CHAT connection (allowing you
 +to initiate a [[DCC]] [[DCC SEND|SEND]],​ for example), if the remote client
 +supports CTCP-over-DCC. ​ EPIC clients will work; others may or may not.
 +The [[DCC]] CHAT connection persists until either the connection is 
 +voluntarily closed by either party using [[dcc]] [[dcc close|close]],​ or
 +when either party terminates their client.
 +If you offer a [[DCC]] CHAT connection and the other person does not accept it,
 +you can re-tender the offer by using [[DCC]] CHAT again. ​ This will send a
 +duplicate [[CTCP]] message to the other peer, to let them know that you are
 +still offering the connection.
 +If the -p flag is present you may specify the port that the client
 +should use for the connection.
 +All the usual caveats about using [[dcc]] behind a NAT router apply.
 +   /dcc chat bob Offer a DCC CHAT connection to "​bob"​ on
 + the current network.
 +   /msg =bob Hi there bob! Send a message to "​bob"​ over DCC CHAT after
 + bob has accepted the connection. ​ If bob
 + changes his nickname on irc, you would still
 + use "​=bob"​ to send him a DCC CHAT message.
