I agree you and your chapter are showing true panhellenic spirit ! I know that when I went through rush... (although it was informal) at open house one of the houses had members from a nearby school talking to us. I don't think there is anything against the rules about it and it was classy of the chapter to let everyone know what was going on. I can't believe that there are chapters who aren't supporting this. I mean there's really nothing they can do about it anyway.. since the chapter bringing in visitors has already told Panhel, I'm sure they'll tell the rushees... so the larger houses telling the PNMs they are being rushed by sisters who don't belong to the chapter they would be joining is moot anyway, but it is sad these chapters are acting out of such a non panhellenic spirit.
