-Autonomy. Everyone making decisions about the glo is a current student or alum of the same school. Procedures and policies that do not fit well with the school are non-existent.
-Unless none of the alumni ever leave the area, there is still a nationwide network to benefit from - and every alum contacted has a double connection, to the school AND the glo. Even members of national groups often say t . hey feel more connection with someone from a different Greek group from their school, than they do a sister or brother whose school and/or chapter was very different from their own.
