here's the link to the International policy online
Phi Sig recruitment policy
[QUOTE]Special consideration is defined as being invited to all invitational parties before the Preference party unless the chapter has determined that the legacy is definitely not a prospective member or the legacy has chosen not to accept an invitation to return to a party. If the chapter makes the determination not to consider the legacy for membership, that decision must be approved by the chapter advisor (or membership recruitment advisor or division collegiate president) after consultation with their regional collegiate director.[QUOTE]
also i agree, Jess, tell her all you know, and of course preface that it could just be rumours, but it's your experience/knowledge. Let her know it's ok to really make her own decision, but also if anything goes on that she's uncomfortable with, she can always talk to you.
And remember, just because you think your sister is too preppy for that chapter, she still might fit in...my chapter is weird that way because we have women with very different personalities and interests but still get along.
