Hi CityStyleChick!
I attended WSU (a couple years back) and I also went through recruitment. The Greek system is wonderful at WSU and will be glad you became involved. I suggest you check out the website for Greek Life on campus:
http://www.wsu.edu/hdrl/Greek/greek.htm
The website will give you a lot of information about each sorority.
I hope this helps! Personally, I think the Alpha Gamma Delta Chapter there is awesome! PM me if you would like some more info on AGD.
Good luck and enjoy recruitment! Follow your heart...greek membership lasts a lifetime. :-)
