a member sends one atack a night and 1 defence a night is it me or does that leave 1 free fleet?
my guess is that any "joint" bg is the bg's leader's attempt to hit an alliance (or several alliances) he doesn't like.
I have organised several BG's for various groups of players over the rounds and I can tell you that I worked around alliance rules to ensure I could choose my own targets.
I think if sid really is grasping on a joint bg he had better be sure of joint command liason as any other information is just crap. At the end of the day everyone wants roids and the good players will look for several targets from several sources.
I personally see this as nohing more than 1up attempting touse alliances to ensure there own safety and stability to follow that with a lengthy period of 1 alliance stagnation.
Similar to round 3 or so.
You gotta love the ol stye propagnada though
