Sounds like hogwash to me. I have a different address from my son (two towns away), yet I am the ACM for his Pack, and when he was in a Tiger den, I was usually his adult partner. He only has one application on file- with his mother's address on it. That is where he lives 5 out of 7 days of the week. In addition, there is nothing that I have seen written anywhere that states that only one person can be the adult partner- it can be a parent, grandparent, older sibling, etc. It can be a different person at each meeting as far as I know, as long as there is an adult with the Scout. There is no reason that each person who might conceivably be at a Den or Pack event would have to fill out a separate Youth Application. Your second concern doesn't mean anything unless you can be a little more concrete about what you didn't like.
