Notes:
Your public tagging is visible and searchable by all users. All users will also be able to read tagging notes for publicly visible tags. Public tagging is also permanent. You may NOT edit notes on your public tagging.

Your private tagging is only visible and searchable by yourself. You may use private tags to help organize and compose searches and selections. You may edit notes that describe your private tagging. Private tagging expires a week after creation, unless you make them them public.
