Manda, GC is probably the MOST panhellenically minded community you'll ever see! And if "rush silence" applied to the internet, GC would have to shut down for around 4 weeks twice a year to meet every school's formal rush & informal rush schedules.
That said, great to hear you had such a good time. I have some questions though....
(1) What do you want out of a sorority? I'm just curious -- some girls join to meet other girls, some girls want the tradition, some want the additional help with school, some want a more robust social life. There's as many reasons as there are sorority members, I think.
(2) Did you have a favorite sorority in mind going into rush?
(3) Have any of the sororities surprised you so far?
(4) Any theories yet on which houses your Rho Deltas are from?
(5) What did you mean by saying the one group was "out of your reach"? The only meaning I could figure out is that you felt like the girls wouldn't list you for their return parties. Is that what you meant?
