I'm a computational chemist who did some minor editing before 2020, created a couple of starter pages in 2020, and now in 2024 have more time to create new pages and expand others, in particular for women scientists and rabbis but I find myself working on others as well. I’m also drawn to fixing citation errors and trying to find missing citations.
Wish I'd found this citation tool earlier. It creates a filled-in, properly formatted citation template if you provide a DOI, URL, or ISBN value.
Also wondered how many people are active on English Wikipedia and with the "Wikipedia size & users" template I know the answer.
