Counting IDs made per identifier during an ID-a-thon?

An ID-a-thon is an identification marathon, where participants work hard to ID as many Needs ID observations as possible in a specified period of time. They certainly aren’t just reserved for animals. We’re not supposed to advertise projects on the form (understandably; otherwise, we’d be flooded with Join Us appeals!), so I can’t point you to particular ID-a-thons, but maybe if you go search projects on the iNat website, you’ll come up with some that interest you.
