Did you also happen to read this?

It's at the VERY TOP of the AKA forum. No matter how innocent the question may seem, membership questions are not answered here. Seeing as how you were asking how you can contact a graduate chapter about membership, that question falls into that category.
Do not be mad at AKA2D'91 because she knew how to seek membership, and did not spoonfeed the information to you. No one knows you or what you have to offer, and therefore does not have to coddle you. So, direct the frustration where it really belongs: at yourself because
you don't know how to proceed.
