I could be wrong, but I believe there was only one group not taking quota and not at total and I don't think they are going to COB.
I believe ZTA took quota and is at total.
Of course, there may be groups losing members to spring/summer graduation. So, she may have some luck there.
Your best bet is to have her contact the office of Greek life. It's in the KUC 3rd floor if she wants to go up there...
And, I'll interject a shameless plug for Crystal (mtsugurl) and her PhiChi girls
You might have her contact them, as they are some of the most awesome girls! You can ask her if they are still doing Spring rush...
