I like that this will discourage IDs for the sake of climbing the leaderboard. On the other hand I wish the threshold was slightly higher - like three IDs, to encourage review. I frequently find a lot of “RG” observations with only two identifiers and incorrect IDs. Often this is when the original observer has no clue but “agrees” with the first ID someone else offers.
Many species have discernible subspecies that are important to consider for conservation reasons. With this change, if I add a subspecies to an observation that is RG at species level, will the subspecies have an “agree” button, or will someone else have to manually add the subspecies to upgrade the ID?
