Example 1 - media removed:
2 species are on the same observation. Observer removes photos of 2nd species, but leaves no comment. I would never have known if observer hadn’t started making additional IDs, which triggered the notifications.
Example 2 - media changed:
changed 1 photo for another. If I hadn’t commented, the identifier wouldn’t have known I changed a pic.
Example 3 - media added:
Added additional pics. Observer added photos from additional angles. If observer hadn’t left a comment, Identifiers would not be notified that new, diagnostically significant photos were now present.
