welcome to greekchat.
by the way, you're still a pi phi
and we have many wonderful pi phis who are active on these boards. you should visit the pi phi forum and introduce yourself.
on greekchat, we try to be supportive of greeklife everywhere and most of us try to remain p.c. when it comes to discussing greeklife at any school. many of us are especially sensitive not to discuss reputations of sororities, whether we are referring to national reps. or a specific chapter.
that being said, i always felt that you can pick up a lot of information just visiting the greek life website of the university you are wondering about. then, by visiting the individual chapter websites you can learn a little more.
unc has a nice greeklife website and the majority of the sororities had websites.
you might also try searching on gc for any rush threads from unc. i seem to remember that we have had some in recent years. that might give you a little more insight. in fact, "mandipepperidge" just completed her rush thread for us, which took place at unc. good luck to your daughter!
