For each mapmaker, counting all maps the mapmaker has been involved in, either as gameplay or graphics developer. Beta maps are counted.
I'm only looking to list currently active mapmakers (active in the foundry, not necessarily making maps right now).
As of 13.4.2011:
Evil DIMwit: 574818 with 4 maps (566690 of which are on doodle earth)
MrBenn: 73144 with 7 maps
Kabanellas: 26056 with 5 maps
Tisha: 23855 with 4 maps
thenobodies80: 22294 with 4 maps
Industrial Helix: 15236 with 4 maps
Dolomite13: 14021 with 2 maps
natty_dread: 10206 with 6 maps

isaiah40: 9678 with 3 maps
Tacktix: 7359 with 1 map
shakeycat: 7344 with 2 maps
The Bison King: 4656 with 2 maps
(to be continued...)
