The All Authors list of NUMA can sort authors by average rating, name, number of maps, number of maps with a public rating, and number of votes placed. When someone mentions an author's position on the list, they always mean when it is sorted by ratings unless they explicity say otherwise. The All Authors list has been a source of controversy, since some users are willing to engage in voting abuse in an attempt to raise their own position on the list, or lower someone else's. Because of this, the the All Authors list is considered inaccurate by many users.
Since NUMA was modified in 2008, the All Authors list has been taken out.
