>>>Actually, each time on this campus we've added another organization no other organization's numbers were really hurt at all. If nothing else more quality men are going through rush<<<


KTSNAKE,
Again, you are talking about MEN going through rush. At the risk of sounding sexist (and I am not) I have to say once more that you just cannot compare the IFC system to NPC. What works for one will not work for the other. Since IFC does not regulate a chapter total for the fraternities on a campus, and there is no quota for recruitment, it doesn't matter as much if a new group is formed.
For sororities, since recruitment is done very formally (hence the name FORMAL recruitment) they do experience a drop in quota and total if a new group comes to campus while one or more groups are struggling - and it does penalize the less strong. It does not serve to spark interest in the greek system as you have pointed out happened when new fraternities came to your school, it only dilutes the system that is in place for sororities to procure new members.
