This was totally not intentional on the PNM's part but:
Last fall I was the computer nerd for recruitment and got to see every single PNM's application so, being occasionally bored while the parties were going on, I'd surf facebook. This girl, who did in fact join our chapter, had a comment on her wall from a guy friend that said he had seen a Sigma Kappa T-shirt and thought of her. From that, I got that this girl was a already in love with Sigma Kappa (her cousin is one, though that doesn't qualify as legacy status). Everyone who had met her at the party was super excited because they liked her so much!
Slightly creepy and facebook stalkerish... yes. But still a positive impression. (As a result of being the computer guru, I had practically memorized these girls on paper... sadly I didn't get to know them as well because I didn't take part in the parties.)
She also had a cute picture for what it's worth.
