informal rush???

All you have to do is to ask that person you met about informal recruitment events or you need to email the recruitment chair of that sorority. You should definitely start talking and and meeting other girls in the sorority you are interested in. Informal recruitment is a great time to meet a bunch of different people in the sorority you wish to join. Realistically, it is the best time to ask a sorority what they are about. Just say this " It was a absolute pleasure meeting you, I would love to meet the rest of the girls in your sorority and I was wondering if you have any recruitment events coming up" Thank you very much.
