It's my understanding that if a PNM voluntarily withdraws she is still eligible for a snap bid as long as she informs Panhellenic that she would be interested. As to whether any snap bids were issued last night or how many Chapters made quota, we won't know that until later. Typically after the Bids are handed out.
