Hi Inca,
I am delighted to hear of another woman who interested in going Greek even after the college days are over!
I read through what you posted and it sounds like you have laid an excellent groundwork thus far!
I am not sure which groups you are interested in but feel free to PM me if you wanted to discuss anything discreetly or if you wanted more in depth advice.
I noticed that you had written:
"There are other groups that are a possibility. I have heard one group doesn't like to do AI's, while two other groups do."
You may need to check out these groups directly and ascetain from there as to how you were received. Although you may not know members directly, once you get to know some of the members in the Alumnae Chapter, you should be able to secure sponsorship from there. I also think that whether they are alumnae in your area and whether they are an
active group should definitely shape your decision.....
I hope that this helps and I look forward to more updates!
