btw personal note = note that only the person who wrote it has value in the note.  If one makes a note that nobody else could possibly understand, this is a personal note.  Notes need to be written in such a way that there is some way that an action can derived from it that will improve the map.  notes like "building site" we get a lot of - and tends to be real estate "professionals" making a pin for their customers to look at - and this usage is forbidden as it'd clog up the note system, and especially for anonymous notes.  Understand now?
