24		-# <http://www.zyx.com/blog>, XML-RPC requests should be sent to
25		-# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the
26		-# Syndication menu, or set up automatic updates under Syndication --> Settings,
27		-# or use a cron job.

	29	+# coming in as it becomes available, you'll have to either check for updates

	31	+# <http://feedwordpress.radgeek.com/wiki/quick-start/> for some details.
