How does this sound

• No consent needed, however wars must be declared
• To declare a war the declaring nation should make a forum post and PM the nation he/she is declaring war on (the PM is just in case the nation war is being declared on doesn't see the post)
• To actually have troops you need to have filled out and posted a link to the regional military spreadsheet. Said spreadsheet can be downloaded here: http://novahistoriae.smfnew2.com/index.php?action=ezportal;sa=page;p=1
• Wars will be turn based. In other words the first person to post should only post a single action declaring units they are moving/using and their actions, the next person to respond will declare any defensive actions taken then units they are moving/using and their action, and so on until all nations involved have posted.
• Nations who are being attacked will have 48 hours to respond to a post/attack. If they do not respond within that time frame it will be assumed that they were unable to defend against that particular attack and the territory/city in question was lost.
