echo urlencode('<br/><a href="' . get_permalink() . '">Read the full story</a>');
?>&amp;subject=<?php echo urlencode(get_the_title()); ?><?php 
$out = array();
if (function_exists('get_the_tags')) { 
  $tags = get_the_tags();
  if ( !empty( $tags ) ) {
    foreach ( $tags as $t ) {
      $out[] = $t->name;
    }
  }
} 
$out[] = get_bloginfo();
echo '&prop_taglist=' . urlencode(join(',', $out));
