The code allows you to control autovoice options for multiple channels. Pretty simple, posted mainly as an example to learn from.

on *:TEXT:!Autovoice*:#: {
  if ($2 == $null) {
    notice $nick Please enter a setting for the autovoice e.g !Autovoice [On|Off]
  }
  elseif ($nick !isop $chan) {
    notice $nick You must be an op to set the autovoice settings for #
  }
  elseif ($2 == $readini(autovoice.ini, $chan, setting)) {
    notice $nick Your setting is already set to $readini(autovoice.ini, $chan $+ , setting)
  }
  elseif ($2 == on) {
    /writeini autovoice.ini $chan setting $2
    notice $nick Autovoice settings for $chan set to: $2
  }
  elseif ($2 == off) {
    /writeini -n autovoice.ini $chan setting $2
    notice $nick Autovoice settings for $chan set to: $2
  }
}
on *:join:#: {
  if ($readini(autovoice.ini, $chan, setting) == on) && ($me isop $chan) {
    /mode $chan +v $nick
  }
  elseif ($readini(autovoice.ini, $chan, setting) == on) && ($me ishop $chan) {
    /mode $chan +v $nick
  }
}
