I can safely say that the SAI chapter at my school is definitely not the same as NPC sororities.. But not so different either.

They have certain ummm practices that would threaten the charter of an NPC org (my friend's wife pledged and I know a little of what goes on there).

Their biggest recruiters are teachers in the music department.... And I don't know of a single person that is in both a regular sorority and SAI... I don't think they necessarily bill themselves as the "anti-sorority" -- but music majors up til recently have not been greek... PKA somehow bridged that gap though on the men's side.

Yes they're Greek (if that's what you call yourself than who am I to say otherwise?)... But Greek in the same sense that I am, I'd say not.
