Lancer -- Strict communication through private e-mail will be the way of things. Might as well book in that the address will be JenaCampaignATgmailDOTcom. Pleased that was available.
I anticipate a brief period at the beginning for organization and coordination between the commander and subordinates -- planned course of action and all that -- after which comms go dark and everybody loses everybody else unless they're within 10km of one another. This is, of course, entirely honor system, but, as there's greater glory in losing bravely than in winning knavishly, I should think that little problem.
The only thing I'm still working out with the management is how to provide a look in for those not playing on the game's progress.
