Yea no more minivans!
As for the barbeque dealio I think that the right think to do would just be that everyone the day before post what they are bringing. Say 10 people post: Ill bring drinks in a cooler, ill bring cups and plates, ill bring meat, ill bring buns, etc.
Its alot easier than it sounds, and all we would have to do would be stop at dominicks right before you get there, bada bing bada boom!
Yay Barbeque!
