No worries.
There is a spot where you can scramble your whole novel before you verify the word count. I would have to search around for it, I haven't used it yet.
There are some people on there who have gotten their novels published after they wrote it, so you never know. You might write something worth submitting to an agent.
Here is a link to a contest going that they posted in their blog on nanowrimo. Not done through the nanowrimo people though.
If it's a young adult novel you can send them your title and the first 250 words of your novel. If you get first place I think you can pitch yout book to them. No guarantees but it would still be cool to pitch your book, even if nothing comes of it.
If you're in the first 20 I think you get a copy of a book written by the agent running the contest.
