Yeah, basically, the maps linked in the Opening Post and the Battlelog (when it gets posted) will be kept up to date by us. We don't really want them being altered by players because it might cause confusion; if you forget to update the map, or update it incorrectly, it could cause confusion if it clashes with the official map. Plus, the GM's might need to add small details or change small details that would be missed if people had their own maps in their Headers. So for now, at least, just leave the map editing to the GM's. We'll make sure everybody is where they need to be :P
