I also wanted to add that the National Tri Delta officers I spoke with preferred to contact the "local" groups or individuals first, for me, rather than me contacting the locals directly. This was to eliminate any confusion.
At least twice that I can remember (before I was introduced to the woman who eventually sponsored me and just prior to my initiation) Tri Delta's honor initiate coordinator told me she would contact the necessary people first so that she could explain that she was the person in charge of Tri Delta's alum initiation program, what honor initiation is and why she was introducing me to them. I specifically remember being told that most Tri Delta's aren't familiar with honor initiation/alum initiation, which I assumed.
I guess my point here is to suggest that you determine who the national officer is in charge of AI for the group(s) you're interested in, and make ALL your inquiries and follow-ups through that person or persons ONLY, until they can offer introductions for you on the local level.
Just my two cents!
