The NaNo site has an area called the Adoption Society, in case you've not found it yet. It's under the Story Development area. Here's the link...

There are lots of threads with lots of ideas for you to use--Adopt a Plot, Adopt a Subplot, Adopt a Romantic Moment, Adopt a Running Gag, Adopt an Insult, Adopt a Torture, etc. These are all ideas others have posted that are free to use. You can adopt as many as you want and change them to suit your needs. And as many people as want can adopt the same idea because each will use it slightly differently, not to mention, most will never publish.

When reading the ideas, don't just take them at face value. An idea for corporate espionage might not perfectly fit into your romance, but it might spawn the idea of a character trying to sabotage the main character's relationship. An idea about a fairy and orc falling in love could spawn the idea of an alliance between team members of rival teams who have the same goal. Read the ideas with an open mind and think about how each could contribute to your story. Good luck!
