You might want to try doing using the search function and looking up "COB" The rush forum will also be very helpful. I know there was another thread recently (I forget which GLO) that had some good COB ideas. I don't know how formal your COB parties usually are but I think there are several ideas for varying degrees of formality. I'll try to get on later when I have a little more time and post some links for you. In the meantime, welcome to GC
