MESH-Research/commons#122 identified a number of plugins for removal. Remove these plugins from DEV. Ensure that no functionality is lost, or compensate for any that is. Then remove from production.
Public Post Preview
Used on only one site (http://dlsanthology.mla.hcommons.org/). Redundant with Share a Draft, which is used on many more sites. (Although this plugin has more installs on WP.org than Share a Draft and was updated less recently, so maybe we should get rid of Share a Draft instead?)
