Let me explain...not really approval. But for awhile there were so many Pis returning to chapter meetings that they were disruptive. So the advisors asked us to just email or call ahead to make sure there weren't a ton already attending. Now, i can visit if I want to. But if I want to attend it is just a courteousy. It also helps me prepare. If they are having an informal, I'd like to know to dress accordingly, etc.
