Hello! Thanks for contacting "Ask an Advisor."
I don't really have an answer for your question because I'm not sure what you mean by private vs. public issues. If you'd like to resubmit a question with examples, I could try to find an answer.
You might also browse the table of contents of the Community Tool Box (http://ctb.ku.edu/en/table-of-contents) to see if anything provides an answer. In particular, you might refer to the overview section that provides some general info on models for community change (1-2), the chapters on leadership and management (13-16), and maybe the chapters on organizing for advocacy (30-35). I hope you can find something here that will help give you some ideas. Otherwise, feel free to resubmit your question.
