The context is this:
(1) Members release endangered birds into the wild each with a unique leg ring. Every release (and leg ring number) is logged using ACF front end posting on the website.
(2) When birds are found with a leg ring, the finder is also invited to log the location and leg ring number on the website, also using ACF.
(3) When a bird with a matching leg ring number to a release is found, the member who released the bird is notified.
