Like other mentioned I really didnt see the nedd for the Glossary either and after reading a few it did get annoying.
One chnage that I think should happen is that all of the "City-Wide" sororities and Fraternities are NPHC's. To me either they should be stated what they are, i.e National Pan Hellenic, or they should go under nationals (cuz) they are, like the NPC, but it should tell the difference between NPC and NPHC.
