+<p>The chat module contains a few features to make chatting a little nicer.</p>
+
+<dl>
+<dt><b>Smilies</b></dt>
+<dd>Any smiley faces (emoticons) that you can type elsewhere in Moodle 
+    you can also type in here and they will be displayed correctly.  For example,  :-) = <img src="pix/s/smiley.gif">  </dd>
+ 
+<dt><b>Emoting</b></dt>
+<dd>You can start a line with "/me" or ":" to emote.  For example, if your name is Kim and you
+    type ":laughs!" then everyone will see "Kim laughs!"</dd>
+
+<dt><b>Beeps</b></dt>
+<dd>You can send a sound to other people by hitting the "beep" link next to their name.  A useful
+    shortcut to beep all the people in the chat at once is to type "beep all".</dd>
+
+<dt><b>HTML</b></dt>
+<dd>If you know some HTML code, you can use it in your text to do things like insert images, 
+    play sounds or create different coloured and sized text.</dd>
