======Synopsis:======
[[set]] notify [on|off|toggle]

======Description:======
When turned on, the client will periodically poll all of the servers for the 
status of all of the nicks in your [[notify]] list.  The interval between
these polls is [[set notify_intervall]] seconds.

If, during a poll, the status of a nickname has changed (it was previously
online, but is now offline, or it was previously offline, but it is now 
online), then either [[on notify_signon]] or [[on notify_signoff]] will be
hooked, as the case may be.

If this value is turned off, the client will never poll your connected servers
about the nicks in your [[notify]] list and you will not be notified when
a nickname enters or leaves irc.
