  <title>Overview of instant messaging</title>

  <p>
    Instant messaging, sometimes abbreviated to IM, is a text-based means to
    communicate instantly over the internet and the local network. While some
    IM applications work with only one type of account, others, including
    <link xref="introduction">Empathy</link>, provide IM facilities by using
    <link xref="add-account">accounts</link> from different service providers.
    Some of these even support audio and video calling.

  <p>
    Some instant messaging applications can be used to connect to chat rooms,
    online places where like-minded people meet to talk. One popular means to
    connect to several chat rooms is the Internet Relay Chat, also known as
    <link xref="irc-manage">IRC</link>. IRC provides
    <link xref="irc-join-room">public</link> chat rooms, which are open to
    anyone who creates an account on the IRC Server, and private chat rooms,
    which are <link xref="irc-join-pwd">password protected</link>
    and open only to a select few.
