[AOII Angel]

I figured it out too, but I had my doubts because of the names she gave each group! I thought that ADPi was the Triangles (ie Delta!), AOII was the Circles (O), ASA was the stripes (Sigma sort of looks like stripes) or Stars since there are Stars on your website. Once she didn't get a bid and planned to go to the Circle and Stars parties, I figured that the Stars were ASA, and that she would find that she really didn't know enough about the sisters to turn down her bid. I guess she's smart enough not to be this obvious!!
