This is the guide from Wake Forest. I thought it was very comprehensive. As my hs senior was researching the academic side of schools to figure out the best fit for her undergraduate education, I've been looking at the Greek Life sections.
I know one thing my daughter did like seeing on the campuses were the women in their Greek Letters. It made her her more aware of what a strong presence the sororities have on some campuses. So I would put pictures of letter-wearing girls but make sure you have 2 or 3 of each GLO represented in group shots.
