Some useful commands:
/nick new nickname - Changes your nickname.
/me action - Describes an action, for example "/me yawns"
When connecting, you will get a popup stating that this applet is unsafe.
This is a strange thing caused by the fact that the IRC chatbox is not
hosted on the same server as the IRC server. While it is indeed potentially
unsafe, if you trust me, you can trust the applet - click on "No" :)
If you already clicked "yes" because you saw that message before
you saw this message, don't worry - just wait a few and come back to the page from the chat link.
