Here's my first problem with this PNM judging actives issue:
The girls you are looking at are not for sure actives. One of my pledge sisters (who has been an alum for two years but her profile does not indicate the year she graduated) has a Facebook photo that says "all the Gamma Phis toasting X at her wedding" and there are pictures of a bunch of us holding up wine/champagne/cocktails (and yes, even some beer bottles) toasting the bride. We are alumnae! We are allowed to drink alcohol!
If you don't want to join a house where sisters of age are allowed to consume alcohol, then don't. However, suggesting this is really not going to help you, as OTW pointed out in her post. I really think that you should stop posting on GC ASAP if you would like to entertain any thoughts of getting a bid. How many junior transfers will be going through at your school? You are probably very easily identifiable.
