[ ] whenever any user's profile contact address does not have coordinates associated yet, use the default geo location provider to automatically determine them
[ ] when no coordinates can be found, display a form so users can enter coordinates manually (potentially along with an explanation text)
[ ] allow opt-out of automatic coordinate resolution via the settings page
Never fetch the coordinates for the addresses of contacts because this would leak private information without their consent.
