I'm not sure for a solution to that problem, but I do know at my former school, the panhellenic council was usually less than enthusiastic abotu helping small chapters out. This usually caused those chapters to struggle, or close. Before i went there ZTA struggled and is now no longer on campus, which is unfortunate because they are so strong nationally. When I was there four chapters were struggling, which again is really unfortunate because those chapters have great girls in them, and are so strong on a national level. Only two have had recolonization efforts, and of those two, only one has since bounced itself back to great numbers, and the rest still struggle
