As someone who went thru the whole recolonization process, let me tell you...ALUMS can do alot! If it werent for some of our alums, I dont know if we would have come as far as we have. There is some stuff that they couldnt help us with b/c it had been a few years since many were actives, but they helped us to their fullest and it was definately worth it.
With you being an alum, that means you know what your chapter needs better than anyone else. We love all out LC's and appreciate what they did for us, but they were trying to make our chapter into what there chapter was/is. As most know what works from one chapter isnt necessarily going to work for another. Especially if you're from a small one trying to work with a large one. In order to "compete" or stay alive with the others on campus we just couldnt do it. Our alums noticed and took over. We still had the LC's but the alums did most of the job. And its probably the best thing that could have been done. They were there when AGD was huge on campus, so they knew what was needed.
What you can do is volunteer your time like they did and if you held an office, show them how that office works to help the new girls get off the ground. Tell them the kinds of things that you did on campus. Or if you dont have enough time to do that become a Pearl Sister. There is plenty that you can do
