On the promo pages, it says: "If you have had an active Party Poker REAL money account in the past six months, you do not qualify."

So how does the six-month rule work? For instance, if I play at Party Poker, but then cash out and don't play real money for six months, I can sign up again as a new player? Or do you actually have to cancel your account?

I'm curious because I've signed up for about 8 poker rooms now and just don't play at some anymore. If I wait 6 months, can I sign up for them again through PSO without doing anything else, or do I have to cancel them outright?

You need to cancel them and then wait 6 months. You cannot cancel an account you made with PSO and then do the same promotion again 6 months later, however you can do that with an account you made some place else.

So I'll need to email them and tell them to cancel the account--I can't just let it sit and die? Will do!

You got it.
