there have been a couple of general identification blitzes organized by @astra_the_dragon, @arboretum_amy, and others:

if you’re going to organize one for a particular area, i think it’s best to try to attach that to a local bioblitz so that you get local expertise.
i know some folks who gathered local plant experts together at a local nature center one evening of a past City Nature Challenge, with food, etc., for a session of mass identification. however, my understanding is that they experienced technical difficulties, which could have been general CNC-related slowness or too much congestion on their network. however, i sort of suspect they may have been getting throttled since they were probably all working off of the same wifi, and iNat may have interpreted that as a single connection trying to make too many requests.
