The Duke WordPress system was successfully upgraded to version 3.9.1 this morning (Saturday, July 12).
Please note that we removed 12 unused or unsupported plugins from the system. In cases where retired plugins were actively used by Duke WordPress users, we suggested alternative plugins with similar functions: http://sites.duke.edu/blog/2014/06/12/plugins-to-be-removed-during-july-2014-maintenance-window/.

Any feature suggestions received by September 1, 2014, will be considered for our next maintenance window in October 2014.
