One Last Thing is a free and open licensed document that includes Modern GM and Player Best Practices for you to copy/paste/adapt directly into your games.
This was prompted after of two Twitter discussions where we talked about the subject. I looked at all the answers and wrote what I think is a good recap in the form of this document.
This document is available in English and in German!
