One of my favorite parts of NaNoWriMo is NaNoToons!
The comic started with Debbie Ohi and has evolved into a collaborative effort between Errol Elumir and Debbie over the years. You can read their biographies on the page linked above, as well as character bios for past and present characters and find the archive for past NaNoToons all the way back to November 2006. Take my advice and start from the beginning!
Also, you can find a link on the web page to Errol's project NaNoMusical! They are up to episode 3 out of 6 for this video web series and it is fantastic. I'm waiting anxiously for the next one to come out! Good luck to everyone NaNoing this year. We're more than half way through!
Love is love, no matter the back story. <3 DS
