John Carroll is about 10 minutes from my school and I have friends there (one who is a new KD and loving it!!). When I went there on a tour, they said all the orgs were local and so on. I don't know if it's like at my school, where someone some time ago gave a ton of money on the grounds that all the sororities stayed local until 1980-something, but for a long time they couldn't establish any national organizations. Anyhow, I ran into my friend who was a Theta Kappa a few months ago, and she said all the greek orgs. on their campus were being forced to go national this past year, both sororities and fraternities (I know our Sig Eps helped initiate a chapter there). At the time, they were still in the process of looking at the different groups, and I don't know all the details, but she did tell me it was the University that made them go national. My guess would be insurance reasons and such, but who knows, I know none of the decisions my school makes ever make any sense at all.
If I hear anything else from her, I'll post again. None of the sororities here took chapters at JCU, so no one here knows what's going on either, but I'm glad they finally went national!
