My two pennies:
Even though you are a legacy and im sure your mom would love nothing more than for you to get innitiated into her GLO, its important to realize that EVERY chapter is different, they all have their own girls, their own ways of doing things, while your mom may have loved her GLO SOOO much you might not be happy there. every university is going to have a unique chapter, what is special is that they all share the same bond.
my suggestion to u is to go through formal rush, get to meet ALL the sororities,and follow your heart.. you may be surprised at how you feel when u get to know each chapter. I know i was very surprised when i rushed. Im sure your mom will put a reccomendation at the chapter your going to attend. but still look at all the chapters, and go where u feel u will fit in.. this is not just for your college days.. it is for life, and the freinds you make here will follow you throughout your life. Make sure u can be yourself with the house you choose, and the rest will come easily
GOOD LUCK!
