Here's an interesting concept.
University of Alabama Greeks have started "Greek Life Ambassadors."
According to the application, Greek Life Ambassadors are "expected to uphold the values of the Greek community, be knowledgeable about our four Greek Councils, and be able to give tours of the sorority/fraternity residences to prospective students and parents."
