deferred recruitment

OK girls I need your help! This is the first year my campus will be faces deferred recruitment (no freshmen until Januray). Panhellenic is establishing an informal recruitment in fall. I thought I had everyhting under control, but any advice could be used. Since recruitment will be informal how are we, as panhellenic, supposed to monitor the houses so they continue to follow the rules, especially when it comes to dirty rushing. Also any advice on unitizing all the houses would be great.
