CLUELESS

This is an EXCELLENT resource to go to, for answers to your questions: http://panhellenic.tripod.com/FAQ.html
(Full Credit to Barbara "PnguinTrax" of Zeta Tau Alpha, who has helped us all tremendously with our questions).

This will be a great starting point for you to do your research in your decision. Also, don't forget that if you click on the Message Boards, there is one that has the heading "Rush", which is a good resource as well. Good Luck and Happy Researching!
