AI or Collegiate Member?

I'm 22 and just got my BA in May. I didn't join any of the three NPC sororities existing on my campus due to them not being the right "fit" for me and learned there used to be other options on campus so I began inquiries into extension and as a Senior had my idea taken up by two freshman who formed a group of us women into an interest group. Our college has formed an exploratory committee to search NPC groups to consider Coe for colonization. Due to a decision to pursue a teaching license, I'll remain a post-BA student for the next two years and want to stay involved. I just want to know what my membership role can be or what the best role I can fulfilled in a beginning sorority chapter? I'm willing to do anything but just want to be a presence even if it means coming to formal recruitment events or serving in an advisor role.
