ON TOPIC: I know it might not be the greatest idea and it may be tricky to set up, but we could do something of a "kickball" night. In other words we'll have a few captains that choose their teams. You can only have 3 players per guild at a maximum (and no, all of your alternate guilds count as one LD50, :P). I agree that teams that are trying to get better organized should be allowed to queue with their full team or close to it.
I think this is a good suggestion, nights like this, if we had a custum channel that pvpers are talking in, would making planning go much faster.
