The preview servers are all running on voyagerwiki.wisconsin.edu.
Every user login for every campus should be copied there from production zones as of 5/31/2012.
Everyone *needs* to create their own skin to work on customizations. Running multiple instances of the Preview server has been problematic. So, first, please create your own skin, then work on that one.
To work on your instance's Preview files - modify *only* your instance's files, and stop/start your preview server as described below if needed.
