I Googled for a spreadsheet to use to track my NaNoEdMo hours, similar to the one I used for NaNoWriMo, and found this. I created an account (free, only takes about 10 seconds) and copied that to my own account to work on and saved it as this. As you can see I added a few columns. I have saved another copy of it and made it private so that when I update it, this link won’t change. Feel free to copy and alter as you like, no credit to me needed.
