(CNN)No more pre-mixed drinks. Security at the doors. And sober brothers at every event, guarding the stairs and with key access to each room. Those are some of the rules that fraternities will have to abide by if they want to throw a party, the University of Virginia says. UVA shut down Greek social life on November 21, two days after the publication of a now-discredited Rolling Stone magazine article about an alleged gang rape in a fraternity house on the Charlottesville campus. The article's credibility aside, the university acknowledged this week that it needs to evaluate a broader problem, and said the Greek life "pause" was intended to allow leadership to work on improving safety at fraternity and sorority events.

Reinstatement comes with a stipulation that each @placeholder organization agree by January 16 to new rules -- devised by UVA's Greek leadership councils -- for university social events.
