I don't think sorors were trying to be 'elitist' here. The graduate level is different from the undergrad .....membership is by invitation ONLY.
I think the confusion lies in 'we will contact you'....this is a true statement. Since its by invitation only, someone within the organization (an 'active' Soror) must bring you to 'OUR' attention.
So....to all the graduate interests, you may do what you like to make your interest known -- I've know people who have done all sorts of things. You may talk to sorors about the organization and etc. But remember, in the end....membership is by invitation ONLY -- which means its not guaranteed even if you know everyone in the chapter.
Moderators...I know you will edit this if it is inappropriate

But I just thought someone should say something!
SOROR, now you know that WAS TMI! I'm really LMAO!
