I don't think that any sorority can do anything official in terms of membership since you are already a member of an NPC group.. . however as has been said if you find a chapter you get along with and cna hang out with, even though you cant do meetings and such they could still invite you to their events... and I think even if you do have to take alum status you can still serve in some capacity on panhel on your new campus... if not a direct delegate, maybe some sort of advisor. I would suggest contacting them and letting them know you're interested in being involved in greek life even though you don't have a chapter. I know there is a girl at my school who was an ADPI, and we don't have a chapter, so she is giong to be a rho Chi (talk about being impartial!) and she helps out alot with our panhel.
