Coming back to the original post, I wanted to mention another thing that I have done without much scientific or id knowledge (but some local knowledge): I add common names on my language (Spanish) when they are not present in iNat. Here a tutorial for it, if you are interested: https://forum.inaturalist.org/t/how-to-add-a-common-name-to-a-taxon/9792
This is something I can do without knowing much, because I can take the information from wikipedia or field guides.
