Revised Map Challenge Maps/Info Now Available by FTP

At the request of several Map Challenge participants we enabled submission of revised maps/info for 2016 Map Challenge entries in the period between mid-October 2017 and mid-January 2018. We offered this so that updated maps could be archived and referenced, e.g. as part of a contribution to the planned journal special issue.
