For whatever reason, I’ve never gotten in the habit of using the Reviewed button. Since I am not a specialist in anything, I figure one of the useful things I can do is call a potted plant Plants (if I can’t do any better) and check Cultivated. I’ve also gotten to the point where if a photo is blurry, but shows lots of green, I’ll call it Plants and just move on. Ditto for marine life, about which I know scandalously little: does it look like an algae with a reddish tinge? I’ll call it Red Algae and note Maybe?? in the comments. If I’m the only identifier who’s had the time to really look at a particular observation from months ago, I want to say something to get it out of Unknowns. I am happy to be proven wrong if an expert in Red Algae cones along and says nope, that’s a hydrozoan or whatever.
