Giant Bomb's web site doesn't let you convert your unordered list to an ordered one. That's annoying. This makes it less so.

giantbomb-create-ordered-from-unordered-list.js

// create instead of edit
$('form#user-list-form').get(0).action = location.href.replace(/lists(.*)/, 'lists/create/');

// add positions
$('ul#user_list_items li').each(function(index, element) {
  $(element)
    .find('input:first')
    .after('<input type="number" name="user_list[items][' + index + '][position]" value="' + (index + 1) + '">');
  });

// make the new list ordered
$('form#user-list-form').prepend('<input type="radio" id="user_list_unordered_0" name="user_list[unordered]" value="0" checked>');

// change the new list's title
$('#user_list_title').val('Ordered: ' + $('#user_list_title').val());

// save
$('form#user-list-form').submit();
