Synopsis:
   back <back message>]

Description:
   This command marks you as being "back".  It is used to tell people that
   you currently back paying attention to your screen.  You might use it
   after you have taken a nap, a shower, gotten some food. When you mark 
   yourself as back, your status bar will show remove the value of 
   STATUS_AWAY to reflect this; this is "(Away)" by default.

Examples:
   To mark yourself away:
      /back I'm here right now

See Also:
   load(5) away; set(4) beep_when_away, show_away_once, status_away,
   send_away_msg; who(2); whois(2)

Restrictions:
   AWAY status (and messages) is only  through the network once,
   when it is first set.  The implication of this is that, if the AWAY was
   set during a netsplit, when the netsplit heals, the reconnecting servers
   will not be aware of the AWAY status.  Thus, anyone on those servers
   using WHO or WHOIS will not know you are away.  In addition, servers
   will impose a limit to the length of the AWAY message; this is usually
   80 characters; test it on your server to be certain.
