And one last thing:
Code:
on *:Text:!Chr *:?: {
  var %ans = $2
    if (%ans = Sasuke) {
      set $+(%,chr.,$2)
      set $+(%,Lvl1.,1)
      set $+(%,atk1.,6)
      set $+(%,def1.,4)
      set $+(%,spd1.,6)
      /msg $nick You have chosen $2 as your character.
      /msg $nick To view Sasuke's attacks type !Attacks
    }
    if (%ans = Sakura) {
      set $+(%,chr.,$2)
      set $+(%,Lvl2.,1)
      set $+(%,atk2.,6)
      set $+(%,def2.,4)
      set $+(%,spd2.,6)
      /msg $nick You have chosen $2 as your character.
      /msg $nick To view Sakura'a attacks type !Attacks
    }
    else { You already chose a character }
  }
}

How should I set this in an Ini file and how can I stop it if someone already typed !chr whatever.
