I think that the results for Sonoma State (California) maybe incorrect.
A while back LaneSig metioned on the the
2009/2010 Expansions/Colonies/Charters/Closures thread that Sonoma was open for expansion and I thought - Oh no our chapter didn't do well and they are going to expand. Then one day, I was on the National Facebook page and saw something about their 56 new members. If you check out the chapter web page, (
http://www.ssuagd.com/page.php?page_id=113016 ) they mention over 50 new members. So while I don't have any specific knowledge of this chapter, it seems this information may be wrong. All chapters at quota would make more sense for a Panhellenic that was looking to expand.
