bring a new sorority to campus

As many of the sororities know, we have to give bids to a large number of girls. Our sororities are getting really big now, and it is getting to the point where we don't have close bonds and know eachother as well as we should. The chapters are simply getting too big! Instead of adding large amounts of new members to each chapter, why don't we just add one or two more sororities? We only have 8 panhellenic sororities, and most other large state schools have well over 10. What do y'all think?
