I'm sort-of a NaNo. The first year I joined I finished with over 50K words. But the last 2 years in a row, I've just pooped out after a week or so. I just couldn't seem to get anything going. (I've only participated in the November event.)
It's strange. I can write & write & write here on PC, as well as on other websites. The words just flow like the proverbial water! But I get into NaNo & I just seem to go blank... So I wasn't planning to participate in the July Camp... although I did think about it... hm-m-m-m... indecisive... I know...
