What she means is this.
If there's a group of girls on a campus that want to form a chapter of Phi Mu, Phi Mu can't just come to the school and meet them, say "hey! You are awesome! We really dig this school! We want you to be our sisters!" and make them a Phi Mu colony.
They (they as in Phi Mu) have to wait until the campus panhellenic votes to open the campus for expansion.
They have to also make sure National Panhellenic OKs the expansion.
Then, once the campus is officially "open for expansion," any NPC sorority that doesn't have a chapter there can send a packet indicating their interest. Even if these other NPC groups KNOW that the girls on the campus want Phi Mu, if they consider it a desirable expansion opportunity, they will send a packet anyway.
The campus panhellenic looks at all the packets they've received, and picks what they think are the 3 best groups to come and present to them. And guess what? Phi Mu isn't included in the 3.
They went from having a "lock" to not even being in the race.
So to make a long story short (guess it's too late for that), if you feel like you are continually getting hosed when it comes to NPC expansion opportunities, you might not want to be in NPC anymore. And yes, I can see it happening at some point.
(The use of Phi Mu in this story is for dramatic purposes only.
