Wow, I can't believe this.
Sigma Phi Epsilon is one of the top fraternities at Purdue's campus. I have heard rumors about them being shut down for legal issues, but I think that's all they are are rumors. No action has taken place. They continue to thrive.
It's always a shame when a chapter closes. I have met some SK alums who went to IU and they're very sad that their chapter closed. I know if my chapter closed after I graduated, I'd be sad too.
