also you can shorten this

.List Section :{
    %n1 = $$?="1 nickname:"
    %n2 = $$?="2 nickname:"
    %n3 = $$?="3 nickname:"
    %n4 = $$?="4 nickname:"
    %n5 = $$?="5 nickname:"
    %n6 = $$?="6 nickname:"
    %n7 = $$?="7 nickname:"
    %n8 = $$?="8 nickname:"
    %n9 = $$?="9 nickname:"
    %n10 = $$?="10 nickname:"
  }
  .Reset List :{
    %n1 = Empty Slot
    %n2 = Empty Slot
    %n3 = Empty Slot
    %n4 = Empty Slot
    %n5 = Empty Slot
    %n6 = Empty Slot
    %n7 = Empty Slot
    %n8 = Empty Slot
    %n9 = Empty Slot
    %n10 = Empty Slot
  }

to this

.List Section :{ var %^ = 1  | while (%^ <= 10) { set $+(%,n,%^) $$?=" %^ nickname:" | inc %^ } }
  .Reset List :{ var %^ = 1  | while (%^ <= 10) { set $+(%,n,%^) Empty Slot | inc %^ } }

that will do the same thing ur's does.
but anyways nice work...
