I want to thank everyone who's given me their input.
I suppose I just need to take a deep breath, sit down with a friend or two, and ask them these questions. Also, while looking around the forum I came across a thread about community-based greek letter orgs. That got me thinking. Why am I so interested in being a part of a collegiate sorority? Perhaps, I should also keep myself open to the idea of community-based women's societies. That might actually be more fulfilling over the long term; I don't have much time left as an undergrad.
Again, thanks to everyone who replied. I hope you have a pleasant day!
