jQuery.validate + many forms

jQuery.validate can only really deal with 1 form at a time, so if you have many forms on your page, this won't work:

$('form').validate(mySettings);

To get around this limitation, just put a call to .each() in there so that the forms' validation settings are initialised individually:

$('form').each(function() {
  $(this).validate(mySettings);
}
