Geez, 80,000 kids on that campus and she just happens to rush?
At any rate, I think that it would be best if you let these other chapters find out about this girl. If she has no intention of rushing your house, than it's really not up to you to say anything that could affect her rush anywhere else. I think the girls in the other houses are smart enough to see through her

. I think even the most desperate of houses wouldn't let a really crappy PNM in. Plus it's not like there aren't thousands of other girls at OSU who would like bids.
