I usually play games with about one week as deadlines, but if we'd do that the game wouldn't be finished when the mtdg finishes, so 72 hours for normal seasons is fine for me, and about 24-48 hours for retreats/builds. On second thought, I'd prefer Germany, England or Austria (but maybe niklas wants to play that?), but I'd really play anything, except for france of course.
Niklas, how many games of diplomacy have you played? If it's too much to count, then maybe we should let you play in the most challenging position: Austria

Or Italy, if you prefer that
Let's list the prefs to get the thing started soon:
Niklas: Austria/Italy (I know you didn't say that yourself, so please state otherwise if you don't want those!)
Paul: Russia
Peter Grimes: I take it you don't want to play England again so anything but england?
sirdanilot: Germany, England maybe austria
donsig: Italy or Turkey
dl: Anything
Aigburth: anything
Please post if those are incorrect...
Then, we still need a GM! Cubsfan or zyxy? Or maybe the General!

We could also do the following: someone who doesn't participate in the game collects all the orders, and then sends them to me so I can adjudicate them using a nifty little tool I downloaded (RealPolitik) so we can even have cool-looking maps! Or you guys can of course trust me that I will not look at the orders before I write up mine. Or if anyone else has that program, they can do that too, of course (niklas?).
A thread in this forum is a good idea. Wether we use email or pms doesn't really matter to me.
