Sororities, Art School, Atlanta GA, where do i go?

i want my BFA in the fine arts, so i want to go to an art school. Im moving to georgia, and i want to stay in georgia. im going to be living right outside of atlanta. i applied to the art institute of atlanta to get my bfa in the fine arts majoring in film, but i realized that i want to pledge a sorority, as being in a sorority and get you to many places. the only thing is, the art insitutes doesnt have this. is there any way that i can start my own if i wanted to? or how do i go about this situation? i also want to do sports. such as cheerleading and lacrosse, but my school doesnt offer these either. Whats a girl to do?
