23 -# To ensure that fresh content is added as it becomes available, get your
24 -# contributors to put your XML-RPC URI (if WordPress is installed at

28 +# content is added as it becomes available, you can convince your contributors

25 30 # <http://www.zyx.com/blog>, XML-RPC requests should be sent to
26 -# <http://www.zyx.com/blog/xmlrpc.php>), or see `update-feeds.php`
31 +# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the
32 +# Syndication menu, or set up automatic updates under Syndication --> Settings,
