Good afternoon Jane,
Someone sent this to me today and I wanted to make sure that you understand that signs must be hand held. As I had said, we typically mail a letter to confirm and a copy of policies and procedures. Since we didn’t have time for that, I am attaching a copy of the policies – sorry it is so lengthy.
Thank you, Nancy
