This is Zurn's BioShock away system, I just edited & Stuff, 'cause I don't know how to dialog, all credit goes to Zurn. put in remotes and right click, then you'd know what to do..

dialog Sora-Away {
  title "Sora- Away"
  size -1 -1 153 99
  button "[Away]", 1, 9 7 66 27
  edit "Away Reason", 3, 9 69 134 20
  button "[Back]", 2, 80 7 63 27
  edit "Away Nick", 4, 10 41 134 18
}
