And, by the way, Kappa is a great institution and I'm sure has an excellent website, but there are 18 other NPC sororities that are also excellent and also have great websites.
Kappa doesn't have a huge presence in Kentucky and although that's not a deal-breaker it does factor in. Also, there are 2 sororities who HAD chapters at Murray State that are currently dormant. According to NPC rules they are to get consideration in the expansion process (I know I read that on the NPC website but I don't know exactly where). And Kappa may have decided to put all their eggs in the "only schools with more than X number of students or X prestige factor or whatever" basket. So none of this means Kappa wouldn't be invited to colonize at Murray State, but it should give you a clearer idea of the flaws in your thinking.
If you want to help these girls out, you should suggest they read the
www.npcwomen.org website and then talk to their panhellenic. And then I'd step aside. If the girls want this they should be able to work for it without some random guy inputting his two cents.
