In my continuing research on this topic, I just thought I would let you all know that Sigma Kappa has the same policy posted on their website as well. I have been checking most of the NPC websites, and SK was the only one so far that I have found that has the same policy, but I haven't gotten to the large majority of the websites yet, and will be doing so today.
**edited to add: In my cursory perusal of every NPC orgs website I only found 3 that actually put it on the page where I was quickly able to find it and they are: AOII(obviously), Theta Phi Alpha, and Sigma Kappa. If anyone in any other org can find it on your respective website I apologize, I was doing this before I ran off to my class today.**
