WordPress Importer - When you've got a stack of users to import and there's a decent mix of one's that already exist, sorting them out is an unnecessary pain ->

gistfile1.js

jQuery('#authors li').each(function() {
 var $self = jQuery(this);
 var $strong = $self.find('strong');
 var $select = $self.find('select');
 var username = $strong.text().match(/\(([\w]*)\)/);
 var matched = false;
 console.log(username[1])
 if (username) {
  $select.find('option').each(function() {
    if (jQuery(this).text() === username[1]) {
      jQuery(this).attr('selected', true);
      matched = true;
    }
  });
 }

 if (!matched) {
  $self.find('input[type="text"]').val(username[1]);
 }
});
