Weighing in as an Auburn person - you will need a rec (which is the formal form that each sorority has and has to be signed by an alumni of that soriority). Letters of recommendation help keep your name in front of the group (we usually knew if a rushee had a couple of recommendation letters) but you do not want to go overboard as that will also make you stand out. Good luck at Auburn - will be keeping my fingers crossed for you and would love to hear back on your experience.
