Usage: /INVITE <username>
  This  command  allows  you  to  invite  other users, whether in this
  channel  or  not,  into the current channel.  /INVITE by itself will
  display  the  list of users currently invited to this channel.  When
  you  have  invited  the  user(s),  they  will  receive an invitation
  message.   The  invited  users  will  see  the "i" flag set for this
  channel when they do a channel /LISTing.  Only channel operators are
  allowed to use this command.

  Example:
     /INVITE john
     /INVITE jim,bob
