I was wondering if it would be possible to, in any way, sort the amount of bands per country each user has submitted. I'd like to know, for instance, who submitted the most bands from Argentina, and how far behind I am from the top spot (probably waaaay far, but gotta work towards it).

Not much practical use other than maybe just curiosity, but in some scenarios it could help to know who to go to when researching obscure bands.

There is no such feature on the site itself available to regular users, but it can be done with a direct database query.

Top 20 users for bands added with CoO = Argentina. Keep in mind that the query is based on data that's a few months old, but still:

You were #14. (IIRC that's from January this year)

Thanks Azmodes. Hopefully we someday get a search feature for this kind of stuff, it would be very cool.
