My only reason for voting "Nay" is much similar to Bustos, but also there may be an agreement between the two nations at dispute upon the timeframe, and upon objectives, etc. Restricting to a turn based move makes it so that people are forced to log on to write their expansion, which may be prewritten, which means repliers may have to write lengthy responses, and should the "turn" be over what can they do? Maybe I'm not thinking about it right, but Oz has shown in the past that he is dedicated to cartography. Perhaps, instead, he could take on an apprentice?
