I figured it had been asked before, but thought it worth bringing up again!
To answer my own questions:
I'm currently involved at the local level as a dues paying alumnae chapter member. I serve as the President of our local collegiate chapter's (House) Corporation Board. The time and availability commitment for this position fit well for me, and I was asked to fill a need and said yes. I'm glad I did because I've learned a lot.
I'm also a charter member of our Life Loyal AOII program (#58). More info on our program at
www.lifeloyal.org if you're not familiar with how these work. AOII does not have any separate international alumnae dues or fees.
Previously, I've been active as an alumnae chapter member in KY and MA, a member of the AOII Always and Rosevine alum programs (what we had before Life Loyal AOII), an Alumnae chapter officer (Education and Treasurer), and a member of the Alumnae Advisory Committee for my chapter of initiation (served as Chapter Adviser for a few years, and also served as Education, Chapter Relations and Rush/Recruitment adviser before and concurrently with CA).
I'm still involved because I like it. Really, it's just that simple.
