From Roel, during the original network setup: Etherpad is still very bare bones. It is run as user etherpad and the files are in /home/etherpad/etherpad-lite/ . There there is a settings.json you might want to look at. It might be nice to install additional plugins, such as the one that allows you to link to other pads using just the [[padname]]. It stores all the data in an sqlite file, see the settings.json.
