OP, have you looked at the website and Facebook pages for Greek Life at your university? Typically there is information on the different sorority councils and the organizations that are members of the councils. The sites also typically have a section with information on recruitment or intake. The process for joining differs among councils. Have you checked the Greek Life site to see if your university even has a chapter of XYZ? If XYZ is a member of the university's Panhellenic Council, please reread Irishpipes' note above.
