I did a search on thw website and found next to nothing! I looked up sorority, the individual sororities, Greek Life, Rush, Greek Life office, Greek recruitment, recruiment. I found a nice assortment of ROTC recruitment articles, however.
When you search my school's website, most of the results are articles from the school paper, so I did find some articles that gave a "sneak peek" into the Greek life on campus, which was pretty cool. But nothing on rush, really.
