This is just a simple away script, it tells people why you have gone and when you come back it tells them why you left and how long you were gone for... it has a logger for what people need to say to you... just type /away to leave and /away to come back.

Alias Away {
  if (%away == $null) { 
    Away $1-
    set %reason $$?="Why Are You Going?"
    /ame -=-I Am Now Away...-=- | Reason: %Reason | -=- I Am Now Away...-=-
    //set %duration 0
    /inc -c %duration
    /set %away yes
    /window -w @Away
    //echo @away THIS WINDOW WILL SHOW PEOPLE WHO HAVE EITHER SAID SOMETHING TO YOU OR HAVE TRIED TO CONTACT YOU!
    /set %nick $me
    /nick $$?="Change Your Nick To What?"
    halt
  }
  if (%away != $null) {
