Sisters of the University of Georgiaâs chapter of Gamma Sigma Sigma said they joined the non-Panhellenic Council service sorority to reap all the benefits of traditional sorority membership with fewer of what they considered drawbacks: pricey dues, group in-fighting and discriminatory selection processes. In February, some members said they started experiencing some of the downsides they joined Gamma Sigma Sigma to avoid. After a tweet about a memberâs racist blog post went viral, the organization fractured. Over the month, many general members of the chapter and all but one member of the chapterâs executive board resigned. A group of departing members has since founded a separate service society.
