Thanks @bouteloua ! I would be a little sad not to receive “confirming” IDs (as a lay contributor only, it’s a nice reward after posting to see someone “noticing” my observation), but maybe that’s the only way…? The iPhone app does not tell me if the new ID is “disagreeing” with my previous one (I often don’t know if a species-level ID actually disagrees with my original genus-level ID), and the list of notifications just says that someone added an ID, not if the ID disagreed with my original one or not. So I often don’t notice unless someone leaves a GENTLE REMINDER comment that I SHOULD WITHDRAW ORIGINAL ID… ;)
