When I was a Rho Gamma, I was up front with my PNMs that I wanted everyone to go to pref, even if they were less than thrilled about their remaining chapters, even if they seemed sure they would drop after---and they all did. No one dropped out before pref.
I told them to try to resist temptation, but that if they really wanted to find out my affiliation, they probably could (my picture was in the Triangle, nothing I can do about that), but to know that I am keeping their best interests in mind and the best interests on Panhellenic as a whole and not being partial to my own chapter.
Also, I told them not to gossip about chapters, because you shouldn't negatively influence a PNM who might genuinely like a chapter that you talk trash about. I told them to write all negative comments in their book. They were all silent and covering up their cards while ranking after each round.
Along those lines, I told them not to be rude to chapter members. The women you meet really love their chapter. Not being interested is no reason to be rude.
For the sake of keeping your PNMs straight in your head as you write the thread, you might want to change their names to another name that starts with the same letter. (Amanda will be Anne, Heather will be Holly). Or maybe a celebrity they resemble.
I did a thread too:
