The Recruitment Breakdown

So here's the hierarchical recruitment model I've come up with:

• At the top we have recruitment, which refers to fraternities doing that which results in new members.
• This can be divided into passive and active recruitment. The passive sort relates to how our day-to-day operations are perceived, while active recruitment is just as it sounds: actively trying to increase our ranks.
• The most complex method of active recruitment is rush. Rush can be broken into what I have been referring to as passive and active rush. Passive rush is essentially what's done during Orientation, whereas active rush is what begins with the Greek Griller (also known as Rush).
• But there's yet one more level of depth! Active rush consists of two different flavors too. The bulk of the week is indirect rush, where we entertain freshmen with fancy events, free food, and so on. And then the final days are direct rush, where the flashiness goes away and we talk to rushees explicitly about pledging.

But here's a problem. "Passive" and "active" rush are poor terms for what I'm trying to describe. Can you think of anything better? And from a grammatical angle, when should "Rush" be a proper noun?
