I personally have always been a huge advocate of AI. But I was exposed to it very early on--I was initiated into a collegiate chapter that was young, and all but 1 of the members of our local alum chapter were AIs from when we chartered. I think it's a great way to continue to reach out to outstanding women who were unable to become DZs during their collegiate years for a number of reasons.
I do know that some chapters in some areas of the country are not well-informed about AI, and some are resistant, but I think that the opinion is changing, and our national council is all for it.
You can find out about the alums in your area by e-mailing/calling our national headquarters (contact info on the web-site
www.deltazeta.org).
Feel free to PM me if you have any other specific questions. Good luck in your quest!
