I snooped around the InTeen site, and I think I found the
mother lode of InTeen conflicts.
As best I can tell, if you install Inteenminator in place of Teen Woohoo 6, you don't really lose anything.
So... I thought I'd give it a try. At the moment, I've installed all 6 basic Inteenimator files and now I'm running Paladin's Hack Conflict Detector Utility to see what happens. Once I've cleaned up that mess I'll see what kind of mess I can make in my game.
It looks like I'll also need to install a Flavor Pack to have adults remain on campus.
