dfran, while your usage of the American Language and punctuation are very strong, your understanding of the Greek System is not.
It is very simple:
1. You start a Local to affiliate with a National
2. You start a Local to be either a Local or try to grow to become a National. That is that you have Chapters in and at other Schools and States.
To affiliate with a National, it gives you a stronger Name, Sisterhood, Recognition around the country instead of your own little back yard. AB a Local has maybe 35 Alums, but by affiliation with ABC National, you have 1,000's of Alums from all over the world.
We helped a Local Soroity start at PSU, D R. They had an offer to go P M. They said NO, they were happy! Delta Rho lasted 3 years and have been gone for 32. No one remembers them but the maybe 50 ladies that were D R!
I started a Local wanting to affiliate with a Major National, but still ahve thoughts of what could I have done to maybe start a new National. It is Very , Very tough in this day and age.
I dont really know what other information you need or want, and if you do not understand what has been given you here, I suggest that you dont even try!
