This could be handy for so many new users. Not only “Is this wild?”, but “You have left the species blank. Even a general guess like ‘animals’, ‘plants’ or ‘fungi’ helps.” “Uh-oh, you are missing a location. Would you like to add it now (you can mark it private or obscured if you don’t want others to see the location)”, “You’ve attached multiple photos. Do all your photos show the same organism?”
Of course, whether it’s one pop-up or many, it would take a long time to implement: multiple platforms (web, android, iOS), multiple languages, potential latency from the extra steps during times where there are a lot of new users (bioblitzes, city nature challenges, etc), test cycles and testers, etc.
