-Because the software takes some time to install from the repository, it may be a few minutes before the Wordpress intance is in a running state.  One way to check is to login via ssh and ``tail -f /var/log/yum.log``.  Once mysql-server installs, the instance should be ready to go.
+After a few seconds, the ``StackStatus`` should change from ``IN_PROGRESS`` to ``CREATE_COMPLETE``.
