After the suggestion of Nicolas to redo the 2013 survey to find out which are the priorities of the Wikisource Community User Group, I have started this page to gather questions:

Feel free to add your questions, or reshape the content. I have added some additional questions regarding governance and personal involvement that I feel that might be relevant.
