mergers/absorbing other sororities

[angelove]

In the Greek Life forum there is an interesting thread about mergers of NPC sororities and larger NPC sororities absorbing smaller sororities (not locals that become chapters). this made me wonder - has Pi Phi ever absorbed or merged with another NPC or major sorority? I don't remember ever reading about any mergers or even absorbing anyone major, but maybe I missed something? It seems like it would have been in the pledge manual or something if we actually did. I just keep reading about these other mergers and how the defunct sorority felt that XYZ had the same ideals, so I guess the real question is whether anyone has ever approached us about merger/being absorbed?
