Wouldn't NPC have to vote as a whole and unanimously agree to add another sorority?

I can see some organizations having a problem with that because it would mean sharing Formal Rush and expansion possibilities with yet another group.

If the future hypothetical group had chapters on campuses with a big Formal Rush they could get real competitive real fast. something I could see sororities with chapters on these campus seriously considering.

(editied to add)

So they can peititon to join if they met the qualifications but there is absolutely no guarentee they would be accepted.
