The Hustler has a Feb. 6 article saying that the Vanderbilt administration has banned sorority parties with alcohol until after Spring Break (March 15).

According to the article five of the 10 NPC sororities are currently being investigated "by their national headquarters, as well as by either Vanderbilt University or the Panhellenic Council."
A VU staff member is quoted on the subject of the culture of alcohol. She's against it. Members of a couple of sororities are quoted -- not happy about losing their parties, especially if they are in chapters that didn't break rules.
Apparently after Spring Break sororities without alcohol problems / infractions will be able to have parties again. Not clear about what might happen with others.
Guess there will be further developments.
