  ”Notes is a core feature of the OpenStreetMap.org website. It enables you to add a comment on the map to assist others in mapping/editing OpenStreetMap. 
  Please do not use notes for general discussion or storing information not otherwise used in OpenStreetMap. For example please avoid notes such as 'I was here on Saturday' or 'There was a crime at this location'.”
