Well, our list is probably fairly up to date

open downloads.mercenariesguild.net/maps/

Yea, but I'm only posting the maps in the list when they have been released on the mapping forum, seeing how I want everything to link to the topic about the map, so that mappers can just quickly click their link and bump a new release, instead of posting a new one OR just for the people who want to check out a map before downlioading it
