Hmmm...well, the answer to Glitter650's question is yes and no. You don't need hundreds of alumnae to make a colony a success, but it certainly doesn't hurt. And I do believe that it takes more than a handful of alumnae, because only having a handful is a guaranteed way to burn those women out.
Alpha Gamma Delta's newest chapter is located in an area where we didn't have any active chapters nearby, so to some people that might have been interpreted as a sign of "weakness." However, what an third party wouldn't know is that Alpha Gam does have over 2,000 alumnae in the area. We also had two members of our International Council and two members of our Volunteer Service Team nearby. Alpha Gam also committed a Leadership Consultant to the colony throughout their entire colony period and for some time after. While we obviously did not have a need for all 2,000 alumnae in the area to pitch in, we had MANY alumnae volunteering to help in one way or another. Alumnae support is not the end-all-be-all to successfully launching a colony, but it definitely helps.
BTW, the chapter is now at total and very successful. They are the alumnae's pride and joy!
