Overly friendly girls: whatever do you mean?
I'm accustomed to fall recruitment, so I can't really say.
I'm kind of a Greek life fatalist about some things. There's not a lot of tinkering that schools or Panhellenics can do to change the desires and behaviors of 18 years about social groups.
When I stop and think about it, I'm actually pretty impressed at what the NPC is able to do in terms of recruitment and ensuring the success of as many groups as possible, but there's probably a limit.
