Code:
on @10:text:!working:#: .mode $chan +v $nick
on *:text:!add*:*:  work add $nick $2-
on *:text:!rem*:*:  work rem $nick $2-
alias -l work {
  if $2 == starr {
    var %nicks = $replace($3-,$chr(44),$chr(32)), %a = 1, %b = $numtok(%nicks,32)
    while %a <= %b {
      $iif($1 == add,.auser -a,.ruser) 10 $gettok(%nicks,%a,32)
      inc %a
    }
  }
}

1) Replace starr in the above code with the nick you use on IRC.
2) To add one or more people to the list, use !add nick1 nick2 nick3 nick4,nick5,nick6...nickN
2a) Replace the nick representations above with the actual nicks.
2b) Nicks can be space or comma separated.
2c) This command can be sent from the channel or via pm.
3) Removing nicks is similar to adding them, but use !rem rather than !add

I hope this is clear enough. If not, please post back quoting the parts you don't understand and I will attempt to clarify.
