I made an interesting discovery this year: You can now use the NaNoWriMo website to track other writing projects throughout the year, rather than only being able to use it to track progress during regular and Camp NaNoWriMo in November, April, and July.
So this year, following NaNoWriMo, I created a new project for my continuing rewrites after November ended. I was unfortunately unable to just create a new goal for the same project I'd used during NaNoWriMo, but this works just as well since I had to adjust the word count to eliminate the words for some related writing I did during November that wasn't actually part of the novel.
I am really enjoying this new feature of the NaNoWriMo website. I like having a place where I can keep all of my writing projects catalogued in one place, and track progress in all of them. Plus you're able to set an end date for your goal, and the site calculates out how many words you need each day, based on current progress and end goal - just like it does during NaNoWriMo. I am really looking forward to using this feature more than just during NaNo and Camp.
The one feature I wish it had was the ability to put progress bars on your website or blog. In the "old days" of NaNoWriMo, there were word count widgets that pulled your word count from the NaNo site and allowed you to share your progress on your blog. They've since done away with those, but I really wish they still had them, especially now.
For now I'm using a hybrid approach of updating my word count on the NaNoWriMo website to take advantage of the graph and tracking features there, and also using a word count widget I found online some years ago to show my progress on my author blog.
