Well a good way to advertise is in the hall ways and bulletin boards of all the dorms. For us its kewl because a lot of sisters live in all the different dorms. Also, talking up your "classroom buddies" and telling them to come. Even if they don't come, they might tell THEIR friends to come. You have to tell like THE WHOLE WORLD...make sure as many people you know know about the COB. Advertise everywhere, all the popular places, even places off campus, but that you know a lot of people go to. Usually what we do is decorate the house really nice. Get as many sisters (in letters) to show up and put in a kewl chick flick while we do the COB (plus we have tons of food and refreshmants). Thats what my COB was like and it felt great cuz it was nice and comfortable and not at all intimating. The movie gets everyone talking so theres never a a lull in the conversation. Plus the sisters wearing letters shows how close we are and what kewl letters you could have when you join! I hope this helps. GOOD LUCK and I know you guys can bring your numbers up even higher than 40
