The experience was exciting, fun, memorable, and I will totally do it again. I've never been really good with writing so being able to say that I stuck with writing a story that bad for an entire month speaks volumes to how far I've come.
I am currently one of four Municipal Liaisons for NaNo Los Angeles and I run a lot of our social networking outlets.
Hint: it's really easy to write them.
Okay, by "easy" I mean compared to novel writing. Maybe I had better practice from November, but the story came easier and writing was less intense. Compared to my novel, my script needs a lot less editing.
I ran the Script Frenzy region in Los Angeles for two years before the Office of Letters and Light ended the event do to lack of participation. That doesn't mean you shouldn't write a script this April though!
Updates:
September 2012 - Wow, I really haven't gotten back here with updates.
NaNoWriMo
2009 - Haven't looked at it recently, but I could rewrite it into something usable.
2010 - My favorite and most likely to get the needed rewrite/additions. I think it could be published.
2011 - Five partial ideas do not make a full idea. Worst novel ever. The last one thousand pages is me explaining how bad it is.
Script Frenzy
2010 - First and best. Still gets edits and I feel like I need to move stuff around, but it's a good script
2011 - Attempted to make a sequel to the first. Hit one hundred pages and there is no end in sight. Requires complete rewrite.
2012 - Adapted Rosemary and Rue by Seanan McGuire. Not finished, and since there isn't actually a reason to finish... But I did learn a lot about writing from the experience.
