Usage: SET AUTO_REJOIN [ON|OFF|TOGGLE]
  If set to ON, it will automatically re-join you to any channel from
  which you are kicked.  It is superior to most script packs in terms
  of speed.  It is also able to correctly re-join channels with the
  mode +k set (channel password), which most script packs cannot handle.

  If set to OFF, you will never automatically rejoin a channel from 
  which you are kicked, unless of course, you have a script alias to do
  so.  You should have this turned OFF if you are going to use a script
  alias to auto-rejoin yourself.
