I'm right there with AGDee. If a new member wants to depledge, the campus will most likely do an interview with them. As an advisor, and not so close to the membership, contact the woman and ask if you can have lunch with her to discuss her leaving the sorority. Make sure she is aware that this is not an attempt to get her to stay, but that you want to know her reasons for dropping and how they can make the NM program and the chapter better for other NMs. Who knows, maybe you'll get them back if you show you really want to change.
