File under housekeeping
We were advised to have at least a placeholder privacy policy and data retention policy; about two months ago Nadia went public with it in this post in the Agora – you must have missed it. You are welcome to improve upon it. If you want to initiate a consultation on this, go right ahead, with our thanks, as – you guessed it – who does the work calls the shots. 
You misinterpreted my post. The original ER website was CC-BY, not CC0, and I still believe that to be the best license for user-generated content as it protects the right to be acknowledged as author. Some lawyers say CC0 does not work with the European legal framework on moral rights (which include the right to be acknowledged as author), because the latter are unmovable: you are not allowed to renounce your legal rights. From an interoperability point of view, however, CC0 does not break interoperability in Edgeryders.
